Detailed Description

Specialized error type for RPC methods.

Instances of this type, when thrown in a method handler, will have their code, message, and optional data serialized into a proto::RpcError and sent across the wire. The caller will receive an equivalent error on the other side.

Built-in errors are included (codes 1400–1999) but developers may use arbitrary codes as well.

Constructor & Destructor Documentation

RpcError() [1/2]

livekit::RpcError::RpcError	(	std::uint32_t	code,
		std::string	message,
		std::string	data = {}
	)

Construct an RpcError with an explicit numeric code.

Parameters

code	Error code value. Codes 1001–1999 are reserved for built-in errors (see ErrorCode).
message	Human-readable error message.
data	Optional extra data, e.g. JSON. Empty string means no data.

RpcError() [2/2]

livekit::RpcError::RpcError	(	ErrorCode	code,
		std::string	message,
		std::string	data = {}
	)

Construct an RpcError from a built-in ErrorCode.

Parameters

code	Built-in error code.
message	Human-readable error message.
data	Optional extra data, e.g. JSON. Empty string means no data.

Member Function Documentation

builtIn()

static RpcError livekit::RpcError::builtIn ( ErrorCode  code, const std::string &  data = {}  )

static

Create a built-in RpcError using a predefined ErrorCode and default message text.

Parameters

code	Built-in error code.
data	Optional extra data payload (JSON recommended).

code()

std::uint32_t livekit::RpcError::code ( ) const

noexcept

Numeric error code.

Codes 1001–1999 are reserved for built-in errors. For built-ins, this value matches the underlying ErrorCode enum value.

data()

const std::string & livekit::RpcError::data ( ) const

noexcept

Optional extra data associated with the error (JSON recommended). May be an empty string if no data was provided.

message()

const std::string & livekit::RpcError::message ( ) const

noexcept

Human-readable error message.
