Struct Context 

pub struct Context {
    pub conn_id: ConnectionId,
    pub request_id: RequestId,
    pub method_id: MethodId,
    pub metadata: Metadata,
    pub channels: Vec<u64>,
}

Context passed to service method implementations.

Contains information about the request that may be useful to the handler:

• conn_id: Which virtual connection the request came from
• metadata: Key-value pairs sent with the request

This enables services to identify callers and access per-request metadata.

Fields

conn_id: ConnectionId

The connection ID this request arrived on.

For virtual connections, this identifies which specific connection the request came from, enabling bidirectional communication.

request_id: RequestId

The request ID for this call.

Unique within the connection; used for response routing and cancellation.

method_id: MethodId

The method ID being called.

metadata: Metadata

Metadata sent with the request.

This is the metadata field from the wire Request message.

channels: Vec<u64>

Channel IDs from the request, in argument declaration order.

Used for stream binding. Proxies can use this to remap channel IDs.

Implementations

impl Context

pub fn new( conn_id: ConnectionId, request_id: RequestId, method_id: MethodId, metadata: Metadata, channels: Vec<u64>, ) -> Self

Create a new context.

pub fn conn_id(&self) -> ConnectionId

Get the connection ID.

pub fn request_id(&self) -> RequestId

Get the request ID.

pub fn method_id(&self) -> MethodId

Get the method ID.

pub fn metadata(&self) -> &Metadata

Get the request metadata.

pub fn channels(&self) -> &[u64]

Get the channel IDs.

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Context

fn fmt(&self, f: &mut Formatter<'_>) -> Result
