pub struct CTFramesetter(_);

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.

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

Performs copy-assignment from source.

impl ConcreteCFType for CTFramesetter

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 Eq for CTFramesetter

impl PartialEq<CTFramesetter> for CTFramesetter

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl TCFType for CTFramesetter

type Ref = CTFramesetterRef

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.

pub fn as_CFType(&self) -> CFType

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

pub fn into_CFType(self) -> CFType

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

pub 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.

pub fn type_of(&self) -> usize

Returns the type ID of this object.

pub fn show(&self)

Writes a debugging version of this object on standard error.

pub fn instance_of<OtherCFType>(&self) -> bool where
    OtherCFType: TCFType, 

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