[−][src]Struct rustc_passes::region::Context

pub struct Context {
    root_id: Option<ItemLocalId>,
    var_parent: Option<(Scope, ScopeDepth)>,
    parent: Option<(Scope, ScopeDepth)>,
}

Fields

root_id: Option<ItemLocalId>

The root of the current region tree. This is typically the id of the innermost fn body. Each fn forms its own disjoint tree in the region hierarchy. These fn bodies are themselves arranged into a tree. See the "Modeling closures" section of the README in rustc_trait_selection::infer::region_constraints for more details.

var_parent: Option<(Scope, ScopeDepth)>

The scope that contains any new variables declared, plus its depth in the scope tree.

parent: Option<(Scope, ScopeDepth)>

Region parent of expressions, etc., plus its depth in the scope tree.
