Trait CanonicalExt

pub trait CanonicalExt<'db, V> {
    // Required methods
    fn instantiate(
        &self,
        tcx: DbInterner<'db>,
        var_values: &CanonicalVarValues<'db>,
    ) -> V

}

Required Methods

fn instantiate( &self, tcx: DbInterner<'db>, var_values: &CanonicalVarValues<'db>, ) -> V

where V: TypeFoldable<DbInterner<'db>>,

fn instantiate_projected<T>( &self, tcx: DbInterner<'db>, var_values: &CanonicalVarValues<'db>, projection_fn: impl FnOnce(&V) -> T, ) -> T

where T: TypeFoldable<DbInterner<'db>>,

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl<'db, V> CanonicalExt<'db, V> for Canonical<'db, V>

FIXME(-Znext-solver): This or public because it is shared with the new trait solver implementation. We should deduplicate canonicalization.
