Implementations

impl CTGlyphInfo

pub unsafe fn with_glyph_name( glyph_name: &CFString, font: &CTFont, base_string: &CFString, ) -> Option<CFRetained<CTGlyphInfo>>

Available on crate feature CTFont only.

Creates an immutable glyph info object.

This function creates an immutable glyph info object for a glyph name such as “copyright” and a specified font.

Parameter glyphName: The name of the glyph.

Parameter font: The font to be associated with the returned CTGlyphInfo object.

Parameter baseString: The part of the string the returned object is intended to override.

Returns: This function will return a reference to a CTGlyphInfo object.

pub unsafe fn with_glyph( glyph: CGGlyph, font: &CTFont, base_string: &CFString, ) -> Option<CFRetained<CTGlyphInfo>>

Available on crate features CTFont and objc2-core-graphics only.

Creates an immutable glyph info object.

This function creates an immutable glyph info object for a glyph index and a specified font.

Parameter glyph: The glyph identifier.

Parameter font: The font to be associated with the returned CTGlyphInfo object.

Parameter baseString: The part of the string the returned object is intended to override.

Returns: This function will return a reference to a CTGlyphInfo object.

pub unsafe fn with_character_identifier( cid: CGFontIndex, collection: CTCharacterCollection, base_string: &CFString, ) -> Option<CFRetained<CTGlyphInfo>>

Available on crate feature objc2-core-graphics only.

Creates an immutable glyph info object.

This function creates an immutable glyph info object for a character identifier and a character collection.

Parameter cid: A character identifier.

Parameter collection: A character collection identifier.

Parameter baseString: The part of the string the returned object is intended to override.

Returns: This function will return a reference to a CTGlyphInfo object.

pub unsafe fn glyph_name(self: &CTGlyphInfo) -> Option<CFRetained<CFString>>

Gets the glyph name for a glyph info, if applicable.

This function will return the glyph name.

Parameter glyphInfo: The glyph info for which you would like the glyph name.

Returns: If the glyph info object was created with a glyph name, it will be returned. Otherwise, this function will return NULL.

pub unsafe fn glyph(self: &CTGlyphInfo) -> CGGlyph

Available on crate feature objc2-core-graphics only.

Gets the glyph for a glyph info, if applicable.

This function will return the glyph.

Parameter glyphInfo: The glyph info from which you would like the glyph.

Returns: If the glyph info object was created with a font, it will be returned. Otherwise, this function will return 0.

pub unsafe fn character_identifier(self: &CTGlyphInfo) -> CGFontIndex

Available on crate feature objc2-core-graphics only.

Gets the character identifier for a glyph info.

This function will return the character identifier.

Parameter glyphInfo: The glyph info for which you would like the character identifier.

Returns: If the glyph info object was created with a character identifier, it will be returned. Otherwise, this function will return 0.

pub unsafe fn character_collection(self: &CTGlyphInfo) -> CTCharacterCollection

Gets the character collection for a glyph info.

This function will return the character collection. If the glyph info object was created with a glyph name or a glyph index, its character collection will be kCTIdentityMappingCharacterCollection.

Parameter glyphInfo: The glyph info for which you would like the character collection.

Returns: This function will return the character collection of the given glyph info.

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 CTGlyphInfo

fn as_ref(&self) -> &AnyObject

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

impl AsRef<CFType> for CTGlyphInfo

fn as_ref(&self) -> &CFType

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

impl AsRef<CTGlyphInfo> for CTGlyphInfo

fn as_ref(&self) -> &Self

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

impl Borrow<AnyObject> for CTGlyphInfo

fn borrow(&self) -> &AnyObject

Immutably borrows from an owned value.

impl Borrow<CFType> for CTGlyphInfo

fn borrow(&self) -> &CFType

Immutably borrows from an owned value.

impl ConcreteType for CTGlyphInfo

fn type_id() -> CFTypeID

Returns the CFType of the glyph info object

impl Debug for CTGlyphInfo

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

Formats the value using the given formatter.

impl Deref for CTGlyphInfo

type Target = CFType

The resulting type after dereferencing.

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

Dereferences the value.

impl Hash for CTGlyphInfo

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

Feeds this value into the given Hasher.

impl Message for CTGlyphInfo

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

where Self: Sized,

Increment the reference count of the receiver.

impl PartialEq for CTGlyphInfo

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.
