Struct rustc_ast::ast::MetaItemLit
source · pub struct MetaItemLit {
pub symbol: Symbol,
pub suffix: Option<Symbol>,
pub kind: LitKind,
pub span: Span,
}
Expand description
A literal in a meta item.
Fields§
§symbol: Symbol
The original literal as written in the source code.
suffix: Option<Symbol>
The original suffix as written in the source code.
kind: LitKind
The “semantic” representation of the literal lowered from the original tokens. Strings are unescaped, hexadecimal forms are eliminated, etc.
span: Span

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