Struct c2rust_transpile::c_ast::IdMapper

pub struct IdMapper { /* fields omitted */ }

Correspondence between old/new IDs.

We need to re-ID nodes since the mapping from Clang's AST to ours is not one-to-one. Sometimes we need to add nodes (such as 'Semi' nodes to make the lifting of expressions into statements explicit), sometimes we need to collapse (such as inlining 'FieldDecl' into the 'StructDecl').

Methods

impl IdMapper

pub fn new() -> IdMapper

pub fn get_new(&mut self, old_id: u64) -> Option<u64>

Lookup the NEW_ID corresponding to a CLANG_ID

pub fn get_or_create_new(&mut self, old_id: u64) -> u64

Lookup (or create if not a found) a NEW_ID corresponding to a CLANG_ID

pub fn get_old(&mut self, new_id: u64) -> Option<u64>

Lookup the CLANG_ID corresponding to a NEW_ID

pub fn merge_old(&mut self, old_id: u64, other_old_id: u64) -> Option<u64>

If the old_id is present in the mapper, make other_old_id map to the same value. Note that other_old_id should not already be in the mapper.

Trait Implementations
