Struct TemplateContext 

pub struct TemplateContext { /* private fields */ }

Per-request template context shared between middleware and handlers.

TemplateContextLayer populates an instance with request-scoped values (locale, current_url, is_htmx, csrf_token, flash_messages) and inserts it into request extensions before the handler runs.

Handlers access the merged context through the Renderer extractor. Values supplied by a handler override middleware-set values for the same key (handler context wins on conflicts).

Implementations

impl TemplateContext

pub fn set(&mut self, key: impl Into<String>, value: Value)

Inserts or replaces the value stored under key.

Used by TemplateContextLayer to populate request-scoped data, and available to custom middleware that wants to expose values to templates. Note that values supplied by a handler at render time still override values set here.

pub fn get(&self, key: &str) -> Option<&Value>

Returns a reference to the value stored under key, or None if the key is absent.
