-/// A shortcut to link between gRPC request type, response type, client and its
-/// method in order to represent it in a form of types and data.
+/// Macro to implement the `TransportRequest` trait for a given request type, response type, client type, and settings.
+///
+/// # Parameters
+///
+/// - `$request:ty`: The request type for which the `TransportRequest` trait will be implemented.
+/// - `$response:ty`: The response type returned by the transport request.
+/// - `$client:ty`: The client type used to execute the transport request (eg. generated by `tonic` crate).
+/// - `$settings:expr`: The settings to be used for the transport request; these settings will override client's
+///   default settings, but can still be overriden by arguments to
+///   the [`DapiRequestExecutor::execute`](crate::DapiRequestExecutor::execute) method.
+/// - `$($method:tt)+`: The method of `$client` to be called to execute the request.
+///
+/// # Example
+///
+/// ```compile_fail
+/// impl_transport_request_grpc!(
+///     MyRequestType,
+///     MyResponseType,
+///     MyClientType,
+///     my_settings,
+///     my_method
+/// );
+/// ```
+///
+/// This will generate an implementation of the `TransportRequest` trait for `MyRequestType`
+/// that uses `MyClientType` to execute the `my_method` method, with the specified `my_settings`.
+///
+/// The generated implementation will:
+/// - Define the associated types `Client` and `Response`.
+/// - Set the `SETTINGS_OVERRIDES` constant to the provided settings.
+/// - Implement the `method_name` function to return the name of the method as a string.
+/// - Implement the `execute_transport` function to execute the transport request using the provided client and settings.
