Expand description
Resolution for a lifetime appearing in a type.
Variants§
Param
Fields
§
param: LocalDefId
Id of the generic parameter that introduced it.
Successfully linked the lifetime to a generic parameter.
Fresh
Fields
Created a generic parameter for an anonymous lifetime.
Infer
This variant is used for anonymous lifetimes that we did not resolve during late resolution. Those lifetimes will be inferred by typechecking.
Static
Explicit 'static
lifetime.
Error
Resolution failure.
ElidedAnchor
HACK: This is used to recover the NodeId of an elided lifetime.

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.
