        policy: &FormatPolicy,
    ) -> usize { ... }
}

Renders a single grain type into formatted context strings.

Object-safe: stored in RendererRegistry keyed by GrainType.

Required Methods

fn grain_type(&self) -> GrainType

Which grain type this renderer handles.

fn render(&self, grain: &DeserializedGrain, policy: &FormatPolicy) -> String

Full render of the grain’s content.

fn context_priority(&self, grain: &DeserializedGrain, hit: &SearchHit) -> f32

Context priority for this grain [0.0, 1.0].

Provided Methods

fn render_summary( &self, grain: &DeserializedGrain, policy: &FormatPolicy, ) -> String

Compact one-line summary for budget-constrained contexts.

fn token_estimate( &self, grain: &DeserializedGrain, policy: &FormatPolicy, ) -> usize

Estimated token count for the full render (~4 chars per token).

Dyn Compatibility

This trait is dyn compatible.

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