Struct core_text::frame::CTFrame

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

Implementations

impl CTFrame

pub fn get_path(&self) -> CGPath

The CGPath used to create this CTFrame.

pub fn get_lines(&self) -> Vec<CTLine>

Returns an owned copy of the underlying lines.

Each line is retained, and will remain valid past the life of this CTFrame.

pub fn get_line_origins( &self, range: impl Into<Option<CFRange>> ) -> Vec<CGPoint>

Return the origin of each line in a given range.

If no range is provided, returns the origin of each line in the frame.

If the length of the range is 0, returns the origin of all lines from the range’s start to the end.

The origin is the position relative to the path used to create this CTFFrame; to get the path use get_path.

pub fn draw(&self, context: &CGContextRef)

Trait Implementations

impl Clone for CTFrame

fn clone(&self) -> CTFrame

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CTFrame

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

Formats the value using the given formatter.

impl Drop for CTFrame

fn drop(&mut self)

Executes the destructor for this type.

impl PartialEq<CTFrame> for CTFrame

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

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

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

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

impl TCFType for CTFrame

type Ref = *const __CTFrame

The reference type wrapped inside this type.

fn as_concrete_TypeRef(&self) -> CTFrameRef

Returns the object as its concrete TypeRef.

unsafe fn wrap_under_get_rule(reference: CTFrameRef) -> 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: CTFrameRef) -> 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) -> CFTypewhere 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) -> boolwhere OtherCFType: TCFType,

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