impl CodeMetadata

pub const fn empty() -> CodeMetadata

Get a flags value with all bits unset.

pub const fn all() -> CodeMetadata

Get a flags value with all known bits set.

pub const fn bits(&self) -> u16

Get the underlying bits value.

The returned value is exactly the bits set in this flags value.

pub const fn from_bits(bits: u16) -> Option<CodeMetadata>

Convert from a bits value.

This method will return None if any unknown bits are set.

pub const fn from_bits_truncate(bits: u16) -> CodeMetadata

Convert from a bits value, unsetting any unknown bits.

pub const fn from_bits_retain(bits: u16) -> CodeMetadata

Convert from a bits value exactly.

pub fn from_name(name: &str) -> Option<CodeMetadata>

Get a flags value with the bits of a flag with the given name set.

This method will return None if name is empty or doesn’t correspond to any named flag.

pub const fn is_empty(&self) -> bool

Whether all bits in this flags value are unset.

pub const fn is_all(&self) -> bool

Whether all known bits in this flags value are set.

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

The bitwise or (|) of the bits in two flags values.

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

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. remove won’t truncate other, but the ! operator will.

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

The bitwise exclusive-or (^) of the bits in two flags values.

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

Call insert when value is true or remove when value is false.

The bitwise or (|) of the bits in two flags values.

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

The intersection of a source flags value with the complement of a target flags value (&!).

pub const fn complement(self) -> CodeMetadata

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl CodeMetadata

pub const fn iter(&self) -> Iter<CodeMetadata>

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
