OS/2 selection flags

Implementations

impl SelectionFlags

pub const ITALIC: SelectionFlags

Bit 0: Font contains italic or oblique glyphs, otherwise they are upright.

pub const UNDERSCORE: SelectionFlags

Bit 1: Glyphs are underscored.

pub const NEGATIVE: SelectionFlags

Bit 2: Glyphs have their foreground and background reversed.

pub const OUTLINED: SelectionFlags

Bit 3: Outline (hollow) glyphs, otherwise they are solid.

pub const STRIKEOUT: SelectionFlags

Bit 4: Glyphs are overstruck.

pub const BOLD: SelectionFlags

Bit 5: Glyphs are emboldened.

pub const REGULAR: SelectionFlags

Bit 6: Glyphs are in the standard weight/style for the font.

pub const USE_TYPO_METRICS: SelectionFlags

Bit 7: If set, it is strongly recommended that applications use OS/2.sTypoAscender - OS/2.sTypoDescender + OS/2.sTypoLineGap as the default line spacing for this font.

pub const WWS: SelectionFlags

Bit 8: The font has ‘name’ table strings consistent with a weight/width/slope family without requiring use of name IDs 21 and 22.

pub const OBLIQUE: SelectionFlags

Bit 9: Font contains oblique glyphs.

impl SelectionFlags

pub const fn empty() -> SelectionFlags

Returns an empty set of flags.

pub const fn all() -> SelectionFlags

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<SelectionFlags>

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) -> SelectionFlags

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: SelectionFlags) -> bool

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

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

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

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

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

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

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: SelectionFlags) -> SelectionFlags

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: SelectionFlags) -> SelectionFlags

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.
