Enum BindingKind 

pub enum BindingKind {
    Immutable,
    MayJoin,
    MemoryOp,
}

Mutability status of a let-bound variable.

Variants

Immutable

Binding is immutable: assigned exactly once, never escape a case branch boundary. Safe to promote unconditionally.

MayJoin

Binding crosses a case-branch boundary: requires phi-node insertion when promoted.

MemoryOp

Binding is the result of a Reset/Reuse operation and must NOT be promoted (memory semantics must be preserved).

Trait Implementations

impl Clone for BindingKind

fn clone(&self) -> BindingKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BindingKind

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

Formats the value using the given formatter.

impl PartialEq for BindingKind

fn eq(&self, other: &BindingKind) -> 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.
