Enum rustc_mir_build::build::LocalsForNode

enum LocalsForNode {
    One(Local),
    ForGuard {
        ref_for_guard: Local,
        for_arm_body: Local,
    },
}

Variants

One(Local)

In the usual case, a HirId for an identifier maps to at most one Local declaration.

ForGuard

The exceptional case is identifiers in a match arm’s pattern that are referenced in a guard of that match arm. For these, we have 2 Locals.

• for_arm_body is the Local used in the arm body (which is just like the One case above),

• ref_for_guard is the Local used in the arm’s guard (which is a reference to a temp that is an alias of for_arm_body).

Fields of ForGuard

ref_for_guard: Localfor_arm_body: Local

Implementations

impl LocalsForNode

fn local_id(&self, for_guard: ForGuard) -> Local

Trait Implementations

impl Debug for LocalsForNode

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

Formats the value using the given formatter.

Layout

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