Implementations

impl ScopeStackBindings

pub fn new() -> ScopeStackBindings

pub fn get(
    &self,
    variable: ScopeStackVariable
) -> Result<ScopeStack, PathResolutionError>

Returns the scope stack that a particular scope stack variable matched. Returns an error if that variable didn’t match anything.

pub fn add(
    &mut self,
    variable: ScopeStackVariable,
    scopes: ScopeStack
) -> Result<(), PathResolutionError>

Adds a new binding from a scope stack variable to the scope stack that it matched. Returns an error if you try to bind a particular variable more than once.
