Struct MACaptionAppearanceDomain 

#[repr(transparent)]
pub struct MACaptionAppearanceDomain(pub CFIndex);

Available on crate feature MACaptionAppearance only.

MACaptionAppearanceDomain is used to specify which domain of preferences to access.

The user-defined preferences. This domain should be passed to retrieve settings that should be used to render captions.

The system defaults which will not change during a user session. These settings should be used for comparison, not to render captions. For example, when rendering a glyph some caption render engines need to get the user-defined font and the system-defined font to determeine the final pixel size to render a glyph. Most render engines will never need to use this domain.

fn clone(&self) -> MACaptionAppearanceDomain

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MACaptionAppearanceDomain

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Ord for MACaptionAppearanceDomain

fn cmp(&self, other: &MACaptionAppearanceDomain) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for MACaptionAppearanceDomain

fn eq(&self, other: &MACaptionAppearanceDomain) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn partial_cmp(&self, other: &MACaptionAppearanceDomain) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
