[+] Show declaration

pub struct Lifetime { /* fields omitted */ }

[−] Expand description

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.
