Enum RangeToNode 

pub enum RangeToNode<'a> {
    Root(RangeToNodeFrame),
    Leaf(RangeToNodeFrame, &'a RangeToNode<'a>),
}

Framed mapping from range to node.

Variants

Leaf(RangeToNodeFrame, &'a RangeToNode<'a>)

Implementations

impl<'a> RangeToNode<'a>

pub fn new() -> Self

Create a new FrameMap.

pub fn last_frame(&mut self) -> &mut RangeToNodeFrame

Get the last frame.

pub fn insert(&mut self, k: EffectRange, v: NodePtr)

Insert a new element into the last frame.

pub fn get_def(&self, def_range: &EffectRange) -> Option<NodePtr>

Get an element from all frames with def range. Returns the element.

pub fn get_use(&self, use_range: &EffectRange) -> Option<NodePtr>

Get an element from all frames with use range.

pub fn branch(&'a self) -> Self

Make a branch on the frame map. Modifications on the new branch will not affect the original one. This is useful when implementing scopes.

Trait Implementations

impl Default for RangeToNode<'_>

fn default() -> Self

Returns the “default value” for a type.
