Trait rustc_transmute::maybe_transmutable::query_context::QueryContext

pub(crate) trait QueryContext {
    type Def: Def;
    type Ref: Ref;
    type Scope: Copy;

    fn is_accessible_from(&self, def: Self::Def, scope: Self::Scope) -> bool;
    fn min_align(&self, reference: Self::Ref) -> usize;
}

Context necessary to answer the question “Are these types transmutable?”.

Required Associated Types

type Def: Def

type Ref: Ref

type Scope: Copy

Required Methods

fn is_accessible_from(&self, def: Self::Def, scope: Self::Scope) -> bool

Is def accessible from the defining module of scope?

fn min_align(&self, reference: Self::Ref) -> usize
