Struct `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.

Fields

apostrophe: Span
ident: Ident

Implementations

`impl Lifetime`

fn new(symbol: &str, span: Span) -> Self

Panics

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