Methods

impl Access

pub const INPUT_ATTACHMENT_READ: Access

Read access to an input attachment from within a fragment shader.

pub const SHADER_READ: Access

Read-only state for SRV access, or combine with SHADER_WRITE to have r/w access to UAV.

pub const SHADER_WRITE: Access

Writeable state for UAV access. Combine with SHADER_READ to have r/w access to UAV.

pub const COLOR_ATTACHMENT_READ: Access

Read state but can only be combined with COLOR_ATTACHMENT_WRITE.

pub const COLOR_ATTACHMENT_WRITE: Access

Write-only state but can be combined with COLOR_ATTACHMENT_READ.

pub const DEPTH_STENCIL_ATTACHMENT_READ: Access

Read access to a depth/stencil attachment in a depth or stencil operation.

pub const DEPTH_STENCIL_ATTACHMENT_WRITE: Access

Write access to a depth/stencil attachment in a depth or stencil operation.

pub const TRANSFER_READ: Access

Read access to the buffer in a copy operation.

pub const TRANSFER_WRITE: Access

Write access to the buffer in a copy operation.

pub const HOST_READ: Access

Read access for raw memory to be accessed by the host system (ie, CPU).

pub const HOST_WRITE: Access

Write access for raw memory to be accessed by the host system.

pub const MEMORY_READ: Access

Read access for memory to be accessed by a non-specific entity. This may be the host system, or it may be something undefined or specified by an extension.

pub const MEMORY_WRITE: Access

Write access for memory to be accessed by a non-specific entity.

pub const fn empty() -> Access

Returns an empty set of flags

pub const fn all() -> Access

Returns the set containing all flags.

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

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

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) -> Access

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

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: Access) -> bool

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

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

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

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

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

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

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