Enum StackNode 

pub enum StackNode {
    PopSymbol(SymbolPop),
    PushSymbol(SymbolPush),
    Root,
    Scope(StackScope),
}

One node of a file’s stack graph: a step in the push/pop path name resolution walks to connect a reference to its definition.

Variants

PopSymbol(SymbolPop)

Pops a symbol, ending the search if it is a definition.

PushSymbol(SymbolPush)

Pushes a symbol to be resolved against a later pop.

Root

The path’s starting point.

Scope(StackScope)

A lexical scope a path may enter while searching for a definition.

Implementations

impl StackNode

pub fn symbol(&self) -> Option<&str>

The symbol this node pushes or pops, for symbol-carrying variants.

pub const fn precedence(&self) -> i64

This node’s resolution precedence; 0 for variants without one.

pub const fn is_reference(&self) -> bool

Whether this node is a reference push (as opposed to an internal relay).

pub const fn is_definition(&self) -> bool

Whether this node pops a true definition (as opposed to a relay or a reference).

pub const fn import_binding(&self) -> Option<&ImportBinding>

The import this definition binds, when it comes from an import.
