`module Route`

Provides operations for parsing and building gRPC request paths.

Definitions

`def self.parse(path)`

Parse a gRPC request path into its service and method names.

Signature

parameter　path　String: The gRPC request path.
returns　Array(String): The service and method names.
raises　ArgumentError: If the path does not contain valid protobuf service and method names.

Implementation

def self.parse(path)
	match = PATTERN.match(path) if path.is_a?(String)
	
	unless match
		raise ArgumentError, "Invalid gRPC route: #{path.inspect}"
	end
	
	[match[1], match[2]]
end

`def self.build(service_name, method_name)`

Build a gRPC request path from its service and method names.

Signature

parameter　service_name　String: The fully qualified service name.
parameter　method_name　String: The method name.
returns　String: The gRPC request path.
raises　ArgumentError: If either component is not a valid protobuf service or method name.

Implementation

def self.build(service_name, method_name)
	unless service_name.is_a?(String) && SERVICE_PATTERN.match?(service_name)
		raise ArgumentError, "Invalid gRPC service name: #{service_name.inspect}"
	end
	
	unless method_name.is_a?(String) && METHOD_PATTERN.match?(method_name)
		raise ArgumentError, "Invalid gRPC method name: #{method_name.inspect}"
	end
	
	"/#{service_name}/#{method_name}"
end
