[][src]Struct syn::Lifetime

pub struct Lifetime {
    pub apostrophe: Span,
    pub ident: Ident,
}

A Rust lifetime: 'a.

Lifetime names must conform to the following rules:

  • Must start with an apostrophe.
  • Must not consist of just an apostrophe: '.
  • Character after the apostrophe must be _ or a Unicode code point with the XID_Start property.
  • All following characters must be Unicode code points with the XID_Continue property.

This type is available if Syn is built with the "derive" or "full" feature.

Fields

apostrophe: Spanident: Ident

Methods

impl Lifetime[src]

pub fn new(symbol: &str, span: Span) -> Self[src]

Panics

Panics if the lifetime does not conform to the bulleted rules above.

Invocation

This code runs with edition 2018
Lifetime::new("'a", Span::call_site())
