Struct LateParamRegion

pub struct LateParamRegion {
    pub scope: SolverDefId,
    pub bound_region: BoundRegionKind,
}

The parameter representation of late-bound function parameters, “some region at least as big as the scope fr.scope”.

Similar to a placeholder region as we create LateParam regions when entering a binder except they are always in the root universe and instead of using a boundvar to distinguish between others we use the DefId of the parameter. For this reason the bound_region field should basically always be BoundRegionKind::Named as otherwise there is no way of telling different parameters apart.

Fields

scope: SolverDefId

bound_region: BoundRegionKind

Trait Implementations

impl Clone for LateParamRegion

fn clone(&self) -> LateParamRegion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LateParamRegion

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for LateParamRegion

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for LateParamRegion

fn eq(&self, other: &LateParamRegion) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
