Implementations

impl CGFont

pub unsafe fn with_platform_font( platform_font_reference: *mut c_void, ) -> Option<CFRetained<CGFont>>

👎Deprecated: No longer supported

Safety

platform_font_reference must be a valid pointer or null.

pub fn with_data_provider( provider: &CGDataProvider, ) -> Option<CFRetained<CGFont>>

Available on crate feature CGDataProvider only.

pub fn with_font_name(name: Option<&CFString>) -> Option<CFRetained<CGFont>>

pub unsafe fn new_copy_with_variations( font: Option<&CGFont>, variations: Option<&CFDictionary>, ) -> Option<CFRetained<CGFont>>

Safety

variations generics must be of the correct type.

pub fn units_per_em(font: Option<&CGFont>) -> c_int

pub fn post_script_name(font: Option<&CGFont>) -> Option<CFRetained<CFString>>

pub fn font_b_box(font: Option<&CGFont>) -> CGRect

pub fn italic_angle(font: Option<&CGFont>) -> CGFloat

pub fn stem_v(font: Option<&CGFont>) -> CGFloat

pub fn variation_axes(font: Option<&CGFont>) -> Option<CFRetained<CFArray>>

pub fn variations(font: Option<&CGFont>) -> Option<CFRetained<CFDictionary>>

pub unsafe fn glyph_advances( font: Option<&CGFont>, glyphs: NonNull<CGGlyph>, count: usize, advances: NonNull<c_int>, ) -> bool

Safety

• glyphs must be a valid pointer.
• advances must be a valid pointer.

pub unsafe fn glyph_b_boxes( font: Option<&CGFont>, glyphs: NonNull<CGGlyph>, count: usize, bboxes: NonNull<CGRect>, ) -> bool

Safety

• glyphs must be a valid pointer.
• bboxes must be a valid pointer.

pub fn glyph_with_glyph_name( font: Option<&CGFont>, name: Option<&CFString>, ) -> CGGlyph

pub fn glyph_name_for_glyph( font: Option<&CGFont>, glyph: CGGlyph, ) -> Option<CFRetained<CFString>>

pub fn can_create_post_script_subset( font: Option<&CGFont>, format: CGFontPostScriptFormat, ) -> bool

pub fn table_tags(font: Option<&CGFont>) -> Option<CFRetained<CFArray>>

pub fn table_for_tag( font: Option<&CGFont>, tag: u32, ) -> Option<CFRetained<CFData>>

Methods from Deref<Target = CFType>

pub fn downcast_ref<T>(&self) -> Option<&T>

where T: ConcreteType,

Attempt to downcast the type to that of type T.

This is the reference-variant. Use CFRetained::downcast if you want to convert a retained type. See also ConcreteType for more details on which types support being converted to.

pub fn retain_count(&self) -> usize

Get the reference count of the object.

This function may be useful for debugging. You normally do not use this function otherwise.

Beware that some things (like CFNumbers, small CFStrings etc.) may not have a normal retain count for optimization purposes, and can return usize::MAX in that case.

Trait Implementations

impl AsRef<AnyObject> for CGFont

fn as_ref(&self) -> &AnyObject

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<CFType> for CGFont

fn as_ref(&self) -> &CFType

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<CGFont> for CGFont

fn as_ref(&self) -> &Self

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<AnyObject> for CGFont

fn borrow(&self) -> &AnyObject

Immutably borrows from an owned value.

impl Borrow<CFType> for CGFont

fn borrow(&self) -> &CFType

Immutably borrows from an owned value.

impl ConcreteType for CGFont

fn type_id() -> CFTypeID

Get the unique CFTypeID identifier for the type.

impl Debug for CGFont

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

Formats the value using the given formatter.

impl Deref for CGFont

type Target = CFType

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Hash for CGFont

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Message for CGFont

fn retain(&self) -> Retained<Self>

where Self: Sized,

Increment the reference count of the receiver.

impl PartialEq for CGFont

fn eq(&self, other: &Self) -> 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.

The Objective-C type-encoding for a reference of this type.

impl Type for CGFont

fn retain(&self) -> CFRetained<Self>

where Self: Sized,
