Struct stack_graphs::paths::ScopeStack

#[repr(C)]
pub struct ScopeStack { /* fields omitted */ }

A sequence of exported scopes, used to pass name-binding context around a stack graph.

Implementations

impl ScopeStack

pub fn is_empty(&self) -> bool

Returns whether this scope stack is empty.

pub fn len(&self) -> usize

pub fn empty() -> ScopeStack

Returns an empty scope stack.

pub fn equals(&self, paths: &Paths, other: &ScopeStack) -> bool

pub fn cmp(&self, paths: &Paths, other: &ScopeStack) -> Ordering

pub fn push_front(&mut self, paths: &mut Paths, node: Handle<Node>)

Pushes a new Node onto the front of this scope stack. The node must be an exported scope node.

pub fn pop_front(&mut self, paths: &Paths) -> Option<Handle<Node>>

Removes and returns the Node at the front of this scope stack. If the stack is empty, returns None.

pub fn display<'a>(
    self,
    graph: &'a StackGraph,
    paths: &'a mut Paths
) -> impl Display + 'a

pub fn iter<'a>(
    &'a self,
    paths: &'a Paths
) -> impl Iterator<Item = Handle<Node>> + 'a

Trait Implementations

impl Clone for ScopeStack

fn clone(&self) -> ScopeStack

Returns a copy of the value.

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

Performs copy-assignment from source.

impl From<ScopeStack> for sg_scope_stack

fn from(stack: ScopeStack) -> sg_scope_stack

Performs the conversion.

impl Niche for ScopeStack where
    List<Handle<Node>>: Niche, 

type Output = MaybeUninit<Self>

The type that is used to store values of Self inside of a ControlledOption. This might be Self itself, if your niche is a valid instance of the type, but which violates some runtime constraint. But if you cannot easily create your niche as an instance of Self, you can use some other type, you can use some other type instead.

fn none() -> Self::Output

Returns the niche value for this type that should be used to represent None for a ControlledOption.

fn is_none(value: &Self::Output) -> bool

Returns whether value is the niche value for this type.

fn into_some(value: Self) -> Self::Output

Transforms a non-niche value of this type into its Output type. When Output is Self, this will be the identity function.

fn from_some(value: Self::Output) -> Self

Transforms a non-niche value of this type from its Output type. When Output is Self, this will be the identity function.
