Enum rustc_middle::middle::resolve_lifetime::LifetimeDefOrigin

pub enum LifetimeDefOrigin {
    ExplicitOrElided,
    InBand,
    Error,
}

The origin of a named lifetime definition.

This is used to prevent the usage of in-band lifetimes in Fn/fn syntax.

Variants

ExplicitOrElided

InBand

Error

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.
