Enum rustc_mir_build::build::LocalsForNode
source · 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 theOne
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 offor_arm_body
).

attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
