pub fn new() -> PartialSymbolStackBindings

Creates a new, empty set of partial symbol stack bindings.

pub fn get(&self) -> Result<PartialSymbolStack, PathResolutionError>

Returns the partial symbol stack that the (unnamed) partial symbol stack variable matched. Returns an error if that variable didn’t match anything.

pub fn add(
    &mut self,
    symbols: PartialSymbolStack
) -> Result<(), PathResolutionError>

Adds a new binding from the (unnamed) partial symbol stack variable to the partial symbol stack that it matched. Returns an error if you try to bind the (unnamed) symbol stack variable more than once.
