Struct hir_def::nameres::DefMap[][src]

pub struct DefMap { /* fields omitted */ }
Expand description

Contains the results of (early) name resolution.

A DefMap stores the module tree and the definitions that are in scope in every module after item-level macros have been expanded.

Every crate has a primary DefMap whose root is the crate’s main file (main.rs/lib.rs), computed by the crate_def_map query. Additionally, every block expression introduces the opportunity to write arbitrary item and module hierarchies, and thus gets its own DefMap that is computed by the block_def_map query.

Implementations

Ascends the DefMap hierarchy and calls f with every DefMap and containing module.

If f returns Some(val), iteration is stopped and Some(val) is returned. If f returns None, iteration continues.

If this DefMap is for a block expression, returns the module containing the block (which might again be a block, or a module inside a block).

Returns the module containing local_mod, either the parent mod, or the module containing the block, if self corresponds to a block expression.
