Trait GenerationHooks

    // Provided methods

Async hooks used by crate::generate_with_hooks.

Rename receives ordered paths after source loading, flattened in configured variant order. Return None to derive names from file stems. Context hooks run only when their matching has_*_context method returns true; CSS runs before HTML. Callback errors are preserved through the associated error type, while engine failures are converted from I/O errors.

Required Associated Types

type Error: From<Error> + Send

Error returned to the caller, including converted engine errors.

Provided Methods

fn rename( &self, _paths: &[String], ) -> impl Future<Output = Result<Option<Vec<String>>, Self::Error>> + Send

Resolve one glyph name per borrowed path, or use the engine’s defaults. Adapters that need an owned callback payload can copy paths inside this method.

fn has_css_context(&self) -> bool

Whether CSS context mutation is enabled.

fn has_html_context(&self) -> bool

Whether HTML context mutation is enabled.

fn css_context( &self, context: Map<String, Value>, ) -> impl Future<Output = Result<Map<String, Value>, Self::Error>> + Send

Mutate the CSS template context before rendering.

fn html_context( &self, context: Map<String, Value>, ) -> impl Future<Output = Result<Map<String, Value>, Self::Error>> + Send

Mutate the HTML context, including styles derived from the finalized CSS context.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
