Struct ContextMap 

pub struct ContextMap { /* private fields */ }

Maps streams/connectors to their assigned context.

Built during Engine::load() by processing ContextDecl statements and StreamOp::Context / Emit { target_context } operations.

Implementations

impl ContextMap

pub fn new() -> Self

pub fn register_context(&mut self, config: ContextConfig)

Register a context declaration

pub fn assign_stream(&mut self, stream_name: String, context_name: String)

Assign a stream to a context

pub fn add_cross_context_emit( &mut self, stream_name: String, emit_index: usize, target_context: String, )

Record a cross-context emit

pub fn has_contexts(&self) -> bool

Check if any contexts have been declared

pub const fn contexts(&self) -> &HashMap<String, ContextConfig>

Get all declared contexts

pub fn stream_context(&self, stream_name: &str) -> Option<&str>

Get the context assignment for a stream

pub const fn stream_assignments(&self) -> &HashMap<String, String>
