Implementations

impl ValueFormat

pub const ANY_DEVICE_OR_VARIDX: ValueFormat

A mask with all the device/variation index bits set

pub fn record_byte_len(self) -> usize

Return the number of bytes required to store a ValueRecord in this format.

impl ValueFormat

pub const X_PLACEMENT: ValueFormat

Includes horizontal adjustment for placement

pub const Y_PLACEMENT: ValueFormat

Includes vertical adjustment for placement

pub const X_ADVANCE: ValueFormat

Includes horizontal adjustment for advance

pub const Y_ADVANCE: ValueFormat

Includes vertical adjustment for advance

pub const X_PLACEMENT_DEVICE: ValueFormat

Includes Device table (non-variable font) / VariationIndex table (variable font) for horizontal placement

pub const Y_PLACEMENT_DEVICE: ValueFormat

Includes Device table (non-variable font) / VariationIndex table (variable font) for vertical placement

pub const X_ADVANCE_DEVICE: ValueFormat

Includes Device table (non-variable font) / VariationIndex table (variable font) for horizontal advance

pub const Y_ADVANCE_DEVICE: ValueFormat

Includes Device table (non-variable font) / VariationIndex table (variable font) for vertical advance

impl ValueFormat

pub const fn empty() -> ValueFormat

Returns an empty set of flags.

pub const fn all() -> ValueFormat

Returns the set containing all flags.

pub const fn bits(&self) -> u16

Returns the raw value of the flags currently stored.

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

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

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

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 intersects(&self, other: ValueFormat) -> bool

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

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

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

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

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

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

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: ValueFormat) -> ValueFormat

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.

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

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

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.
