Struct rustc_hir::definitions::Definitions

source ·
pub struct Definitions {
    table: DefPathTable,
    next_disambiguator: UnordMap<(LocalDefId, DefPathData), u32>,
}
Expand description

The definition table containing node definitions. It holds the DefPathTable for LocalDefIds/DefPaths. It also stores mappings to convert LocalDefIds to/from HirIds.

Implementations§

source§

impl Definitions

source

pub fn def_path_table(&self) -> &DefPathTable

source

pub fn def_index_count(&self) -> usize

Gets the number of definitions.

source

pub fn def_key(&self, id: LocalDefId) -> DefKey

source

pub fn def_path_hash(&self, id: LocalDefId) -> DefPathHash

source

pub fn def_path(&self, id: LocalDefId) -> DefPath

Returns the path from the crate root to index. The root nodes are not included in the path (i.e., this will be an empty vector for the crate root). For an inlined item, this will be the path of the item in the external crate (but the path will begin with the path to the external crate).

source

pub fn new(stable_crate_id: StableCrateId) -> Definitions

Adds a root definition (no parent) and a few other reserved definitions.

source

pub fn create_def( &mut self, parent: LocalDefId, data: DefPathData ) -> LocalDefId

Adds a definition with a parent definition.

source

pub fn local_def_path_hash_to_def_id( &self, hash: DefPathHash, err_msg: &dyn Debug ) -> LocalDefId

source

pub fn def_path_hash_to_def_index_map(&self) -> &DefPathHashMap

source

pub fn num_definitions(&self) -> usize

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
