Struct CFTree 

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

Safe wrapper around a Swift-backed CFTree helper.

Implementations

impl CFTree

pub fn new(value: Option<&dyn AsCFType>) -> Self

Create a tree node with an optional Core Foundation payload.

pub fn append_child(&self, child: &Self)

Append child to this node.

pub fn child_count(&self) -> usize

Number of direct children.

pub fn child_at(&self, index: usize) -> Option<Self>

Copy the child at index.

pub fn value(&self) -> Option<CFType>

Copy the payload value if present.

Trait Implementations

impl Clone for CFTree

fn clone(&self) -> CFTree

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CFTree

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

Formats the value using the given formatter.

impl Hash for CFTree

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 PartialEq for CFTree

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