Trait TemplateLoader 

pub trait TemplateLoader: Send + Sync {
    // Required method
    fn load(&self, name: &str) -> Result<String>;

    // Provided method
    fn cache_key(&self, name: &str) -> Option<String> { ... }
}

Loads template source by name (e.g. "layout.html").

Implement for in-memory maps, filesystem reads, or embedders that fetch from a CDN.

Required Methods

fn load(&self, name: &str) -> Result<String>

Provided Methods

fn cache_key(&self, name: &str) -> Option<String>

When Some, parsed templates for this name may be cached in crate::Environment. Return None for loaders whose sources are not stable by name (e.g. dynamic closures).
