Implementations

impl CallContext

pub fn method(&self) -> &str

Returns the JSON-RPC method name.

pub fn caller_identity(&self) -> Option<&str>

Returns the optional caller identity.

pub fn extensions(&self) -> &[String]

Returns the active extension URIs.

pub fn request_id(&self) -> Option<&str>

Returns the request/trace ID if set.

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

Returns the HTTP request headers (read-only).

impl CallContext

pub fn new(method: impl Into<String>) -> CallContext

Creates a new CallContext for the given method.

pub fn with_caller_identity(self, identity: String) -> CallContext

Sets the caller identity.

pub fn with_extensions(self, extensions: Vec<String>) -> CallContext

Sets the active extensions.

pub fn with_request_id(self, id: impl Into<String>) -> CallContext

Sets the request/trace ID explicitly.

pub fn with_http_headers(self, headers: HashMap<String, String>) -> CallContext

Sets the HTTP headers map (replacing any existing headers).

Automatically extracts x-request-id into request_id if present.

pub fn with_http_header( self, key: impl Into<String>, value: impl Into<String>, ) -> CallContext

Adds a single HTTP header (key is lowercased for case-insensitive matching).

If the key is x-request-id, also populates request_id.
