## MissingLifetime

# Struct MissingLifetime

Source

    pub(super) struct MissingLifetime {
        pub id: NodeId,
        pub id_for_lint: NodeId,
        pub span: Span,
        pub kind: MissingLifetimeKind,
        pub count: usize,
    }

Expand description

Description of an elided lifetime.

## Fields§

§`id: NodeId`

Used to overwrite the resolution with the suggestion, to avoid cascading errors.

§`id_for_lint: NodeId`

As we cannot yet emit lints in this crate and have to buffer them instead, we need to associate each lint with some `NodeId`, however for some `MissingLifetime`s their `NodeId`s are “fake”, in a sense that they are temporary and not get preserved down the line, which means that the lints for those nodes will not get emitted. To combat this, we can try to use some other `NodeId`s as a fallback option.

§`span: Span`

Where to suggest adding the lifetime.

§`kind: MissingLifetimeKind`

How the lifetime was introduced, to have the correct space and comma.

§`count: usize`

Number of elided lifetimes, used for elision in path.

## 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.
