Struct rustc_infer::infer::type_variable::TypeVariableStorage

pub struct TypeVariableStorage<'tcx> {
    values: IndexVec<TyVid, TypeVariableData>,
    eq_relations: UnificationTableStorage<TyVidEqKey<'tcx>>,
}

Fields

values: IndexVec<TyVid, TypeVariableData>

The origins of each type variable.

eq_relations: UnificationTableStorage<TyVidEqKey<'tcx>>

Two variables are unified in eq_relations when we have a constraint ?X == ?Y. This table also stores, for each key, the known value.

Implementations

impl<'tcx> TypeVariableStorage<'tcx>

pub fn new() -> TypeVariableStorage<'tcx>

pub(crate) fn with_log<'a>( &'a mut self, undo_log: &'a mut InferCtxtUndoLogs<'tcx>, ) -> TypeVariableTable<'a, 'tcx>

pub(crate) fn eq_relations_ref( &self, ) -> &UnificationTableStorage<TyVidEqKey<'tcx>>

pub(super) fn finalize_rollback(&mut self)

Trait Implementations

impl<'tcx> Clone for TypeVariableStorage<'tcx>

fn clone(&self) -> TypeVariableStorage<'tcx>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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.
