pub struct FieldInfo {

    pub other_selflike_exprs: Vec<P<Expr>>,
}

Summary of the relevant parts of a struct/enum field.

Fields

span: Span

name: Option<Ident>

None for tuple structs/normal enum variants, Some for normal structs/struct enum variants.

self_expr: P<Expr>

The expression corresponding to this field of self (specifically, a reference to it).

other_selflike_exprs: Vec<P<Expr>>

The expressions corresponding to references to this field in the other selflike arguments.

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.
