Implementations

impl DebugFlags

pub const PROFILER_DBG: DebugFlags = _

Display the frame profiler on screen.

pub const RENDER_TARGET_DBG: DebugFlags = _

Display intermediate render targets on screen.

pub const TEXTURE_CACHE_DBG: DebugFlags = _

Display all texture cache pages on screen.

pub const GPU_TIME_QUERIES: DebugFlags = _

Display GPU timing results.

pub const GPU_SAMPLE_QUERIES: DebugFlags = _

Query the number of pixels that pass the depth test divided and show it in the profiler as a percentage of the number of pixels in the screen (window width times height).

pub const DISABLE_BATCHING: DebugFlags = _

Render each quad with their own draw call.

Terrible for performance but can help with understanding the drawing order when inspecting renderdoc or apitrace recordings.

pub const EPOCHS: DebugFlags = _

Display the pipeline epochs.

pub const ECHO_DRIVER_MESSAGES: DebugFlags = _

Print driver messages to stdout.

pub const SHOW_OVERDRAW: DebugFlags = _

Show an overlay displaying overdraw amount.

pub const GPU_CACHE_DBG: DebugFlags = _

Display the contents of GPU cache.

pub const TEXTURE_CACHE_DBG_CLEAR_EVICTED: DebugFlags = _

Clear evicted parts of the texture cache for debugging purposes.

pub const PICTURE_CACHING_DBG: DebugFlags = _

Show picture caching debug overlay

pub const PRIMITIVE_DBG: DebugFlags = _

Highlight all primitives with colors based on kind.

pub const ZOOM_DBG: DebugFlags = _

Draw a zoom widget showing part of the framebuffer zoomed in.

pub const SMALL_SCREEN: DebugFlags = _

Scale the debug renderer down for a smaller screen. This will disrupt any mapping between debug display items and page content, so shouldn’t be used with overlays like the picture caching or primitive display.

pub const DISABLE_OPAQUE_PASS: DebugFlags = _

Disable various bits of the WebRender pipeline, to help narrow down where slowness might be coming from.

pub const DISABLE_ALPHA_PASS: DebugFlags = _

pub const DISABLE_CLIP_MASKS: DebugFlags = _

pub const DISABLE_TEXT_PRIMS: DebugFlags = _

pub const DISABLE_GRADIENT_PRIMS: DebugFlags = _

pub const OBSCURE_IMAGES: DebugFlags = _

pub const GLYPH_FLASHING: DebugFlags = _

Taint the transparent area of the glyphs with a random opacity to easily see when glyphs are re-rasterized.

pub const SMART_PROFILER: DebugFlags = _

The profiler only displays information that is out of the ordinary.

pub const INVALIDATION_DBG: DebugFlags = _

If set, dump picture cache invalidation debug to console.

pub const TILE_CACHE_LOGGING_DBG: DebugFlags = _

Log tile cache to memory for later saving as part of wr-capture

pub const PROFILER_CAPTURE: DebugFlags = _

Collect and dump profiler statistics to captures.

pub const FORCE_PICTURE_INVALIDATION: DebugFlags = _

Invalidate picture tiles every frames (useful when inspecting GPU work in external tools).

pub const USE_BATCHED_TEXTURE_UPLOADS: DebugFlags = _

pub const USE_DRAW_CALLS_FOR_TEXTURE_COPY: DebugFlags = _

pub const fn empty() -> DebugFlags

Returns an empty set of flags.

pub const fn all() -> DebugFlags

Returns the set containing all flags.

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

pub const fn from_bits(bits: u32) -> Option<DebugFlags>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: u32) -> DebugFlags

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const unsafe fn from_bits_unchecked(bits: u32) -> DebugFlags

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

Safety

The caller of the bitflags! macro can chose to allow or disallow extra bits for their bitflags type.

The caller of from_bits_unchecked() has to ensure that all bits correspond to a defined flag or that extra bits are valid for this bitflags type.

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: DebugFlags) -> bool

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: DebugFlags) -> bool

Returns true if all of the flags in other are contained within self.

pub fn insert(&mut self, other: DebugFlags)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: DebugFlags)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: DebugFlags)

Toggles the specified flags in-place.

pub fn set(&mut self, other: DebugFlags, value: bool)

Inserts or removes the specified flags depending on the passed value.

pub const fn intersection(self, other: DebugFlags) -> DebugFlags

Returns the intersection between the flags in self and other.

Specifically, the returned set contains only the flags which are present in both self and other.

This is equivalent to using the & operator (e.g. ops::BitAnd), as in flags & other.

pub const fn union(self, other: DebugFlags) -> DebugFlags

Returns the union of between the flags in self and other.

Specifically, the returned set contains all flags which are present in either self or other, including any which are present in both (see Self::symmetric_difference if that is undesirable).

This is equivalent to using the | operator (e.g. ops::BitOr), as in flags | other.

pub const fn difference(self, other: DebugFlags) -> DebugFlags

Returns the difference between the flags in self and other.

Specifically, the returned set contains all flags present in self, except for the ones present in other.

It is also conceptually equivalent to the “bit-clear” operation: flags & !other (and this syntax is also supported).

This is equivalent to using the - operator (e.g. ops::Sub), as in flags - other.

pub const fn symmetric_difference(self, other: DebugFlags) -> DebugFlags

Returns the symmetric difference between the flags in self and other.

Specifically, the returned set contains the flags present which are present in self or other, but that are not present in both. Equivalently, it contains the flags present in exactly one of the sets self and other.

This is equivalent to using the ^ operator (e.g. ops::BitXor), as in flags ^ other.

pub const fn complement(self) -> DebugFlags

Returns the complement of this set of flags.

Specifically, the returned set contains all the flags which are not set in self, but which are allowed for this type.

Alternatively, it can be thought of as the set difference between Self::all() and self (e.g. Self::all() - self)

This is equivalent to using the ! operator (e.g. ops::Not), as in !flags.
