Struct RustcPatCtxtState

Source 
pub struct RustcPatCtxtState {
    has_lowered_deref_pat: Cell<bool>,
}
Expand description

Private fields of RustcPatCtxt, separated out to permit record initialization syntax.

Fields§

§has_lowered_deref_pat: Cell<bool>

Has a deref pattern been lowered? This is initialized to false and is updated by RustcPatCtxt::lower_pat in order to avoid performing deref-pattern-specific validation for everything containing patterns.
