Struct ContextFactory 

pub struct ContextFactory { /* private fields */ }

Multi-adapter context factory.

The factory maintains an ordered list of context adapters and composes their output into a single ContextOutput.

Implementations

impl ContextFactory

pub fn new() -> Self

Creates an empty context factory.

pub fn register<A>(&mut self, adapter: A)

where A: ContextAdapter + 'static,

Registers a context adapter.

pub fn register_arc(&mut self, adapter: Arc<dyn ContextAdapter>)

Registers an already shared context adapter.

pub fn len(&self) -> usize

Returns the number of registered adapters.

pub fn is_empty(&self) -> bool

Returns true when no adapters are registered.

pub fn adapter_names(&self) -> impl Iterator<Item = &str>

Returns adapter names in registration order.

pub async fn build(&self, input: &ContextInput) -> ContextResult<ContextOutput>

Builds context output by invoking all adapters in order.

Errors

Returns ContextError::AdapterFailed when any adapter fails.

pub async fn build_request( &self, input: &ContextInput, model: ModelName, tool_specs: Option<&[ToolSpec]>, ) -> ContextResult<ChatRequest>

Builds a ChatRequest with context and optional tool specs.

Pass the tool specs slice (e.g. from behest_tool::ToolRegistry::specs) instead of a typed registry reference to keep behest-context free of a behest-tool dependency.

Errors

Returns ContextError::AdapterFailed when any adapter fails.
