Struct LazyUser 

Source 
pub struct LazyUser { /* private fields */ }
Expand description

A lazily-resolved, per-request template user. The resolver runs at most once (guarded by the OnceCell); resolution happens synchronously from inside minijinja’s sync render via block_in_place.

The lazy value is injected into the template context as a minijinja Object proxy ([LazyUserProxy]). Minijinja calls get_value on the proxy only when the template actually accesses an attribute on user, so requests that never render user skip resolution entirely.

Source§

fn quirk(&self, value: Quirk) -> Painted<&T>
