Struct core_text::framesetter::CTFramesetter

pub struct CTFramesetter(/* private fields */);

Implementations

impl CTFramesetter

pub fn new_with_attributed_string(string: CFAttributedStringRef) -> Self

pub fn create_frame(&self, string_range: CFRange, path: &CGPathRef) -> CTFrame

pub fn suggest_frame_size_with_constraints( &self, string_range: CFRange, frame_attributes: CFDictionaryRef, constraints: CGSize, ) -> (CGSize, CFRange)

Suggest an appropriate frame size for displaying a text range.

Returns a tuple containing an appropriate size (that should be smaller than the provided constraints) as well as the range of text that fits in this frame.

Trait Implementations

impl Clone for CTFramesetter

fn clone(&self) -> CTFramesetter

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CTFramesetter

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

Formats the value using the given formatter.

impl Drop for CTFramesetter

fn drop(&mut self)

Executes the destructor for this type.

impl PartialEq for CTFramesetter

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

impl TCFType for CTFramesetter

type Ref = *const __CTFramesetter

The reference type wrapped inside this type.

fn as_concrete_TypeRef(&self) -> CTFramesetterRef

Returns the object as its concrete TypeRef.

unsafe fn wrap_under_get_rule(reference: CTFramesetterRef) -> Self

Returns an instance of the object, wrapping the underlying CFTypeRef subclass. Use this when following Core Foundation’s “Get Rule”. The reference count is bumped.

fn as_CFTypeRef(&self) -> CFTypeRef

Returns the object as a raw CFTypeRef. The reference count is not adjusted.

unsafe fn wrap_under_create_rule(reference: CTFramesetterRef) -> Self

Returns an instance of the object, wrapping the underlying CFTypeRef subclass. Use this when following Core Foundation’s “Create Rule”. The reference count is not bumped.

fn type_id() -> CFTypeID

Returns the type ID for this class.

fn as_CFType(&self) -> CFType

Returns the object as a wrapped CFType. The reference count is incremented by one.

fn into_CFType(self) -> CFType

where Self: Sized,

Returns the object as a wrapped CFType. Consumes self and avoids changing the reference count.

fn retain_count(&self) -> isize

Returns the reference count of the object. It is unwise to do anything other than test whether the return value of this method is greater than zero.

fn type_of(&self) -> usize

Returns the type ID of this object.

fn show(&self)

Writes a debugging version of this object on standard error.

fn instance_of<OtherCFType>(&self) -> bool

where OtherCFType: TCFType,

Returns true if this value is an instance of another type.
