Source

pub const NEXT_STEP_LATIN: Self

An encoding constant that identifies kTextEncodingUnicodeDefault + kUnicodeUTF16Format encoding (alias of Unicode).

Source

pub const UTF16BE: Self

An encoding constant that identifies kTextEncodingUnicodeDefault + kUnicodeUTF16BEFormat encoding. This constant specifies big-endian byte order.

Source

Source

pub const UTF32: Self

An encoding constant that identifies kTextEncodingUnicodeDefault + kUnicodeUTF32Format encoding.

Source

pub const UTF32BE: Self

An encoding constant that identifies kTextEncodingUnicodeDefault + kUnicodeUTF32BEFormat encoding. This constant specifies big-endian byte order.

Source

pub const UTF32LE: Self

An encoding constant that identifies kTextEncodingUnicodeDefault + kUnicodeUTF32LEFormat encoding. This constant specifies little-endian byte order.

Source

pub const SHIFT_JIS_X0213_00: Self

👎Deprecated

Source

pub const fn empty() -> Self

Returns an empty set of flags.

Source

pub const fn all() -> Self

Returns the set containing all flags.

Source

pub const fn bits(&self) -> CFStringEncoding

Returns the raw value of the flags currently stored.

Source

pub const fn from_bits(bits: CFStringEncoding) -> Option<Self>

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

Source

pub const fn from_bits_truncate(bits: CFStringEncoding) -> Self

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

Source

pub const unsafe fn from_bits_unchecked(bits: CFStringEncoding) -> Self

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.

Source

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

Source

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

Source

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

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

Source

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

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

Source

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

Inserts the specified flags in-place.

Source

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

Removes the specified flags in-place.

Source

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

Toggles the specified flags in-place.

Source

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

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

Source

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

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.

Source

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

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.

Source

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

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.

Source

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

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.
