Enum rustc_infer::infer::DefiningAnchor

pub enum DefiningAnchor {
    Bind(LocalDefId),
    Bubble,
    Error,
}

Variants

Bind(LocalDefId)

DefId of the item.

Bubble

When opaque types are not resolved, we Bubble up, meaning return the opaque/hidden type pair from query, for caller of query to handle it.

Error

Used to catch type mismatch errors when handling opaque types.

Trait Implementations

impl Clone for DefiningAnchor

fn clone(&self) -> DefiningAnchor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DefiningAnchor

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

Formats the value using the given formatter.

impl PartialEq<DefiningAnchor> for DefiningAnchor

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

This method tests for self and other values to be equal, and is used by ==.

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

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
