RPC_CONNECT_RPC_ERROR_CODE: Final = "rpc.connect_rpc.error_code"

The [error codes](https://connectrpc.com//docs/protocol/#error-codes) of the Connect request. Error codes are always string values.
"""

"""
Connect request metadata, `<key>` being the normalized Connect Metadata key (lowercase), the value being the metadata values.
Note: Instrumentations SHOULD require an explicit configuration of which metadata values are to be captured. Including all request metadata values can be a security risk - explicit configuration helps avoid leaking sensitive information.

Connect response metadata, `<key>` being the normalized Connect Metadata key (lowercase), the value being the metadata values.

The [numeric status code](https://github.com/grpc/grpc/blob/v1.33.2/doc/statuscodes.md) of the gRPC request.

RPC_JSONRPC_ERROR_CODE: Final = "rpc.jsonrpc.error_code"

`error.code` property of response if it is an error response.

"""
`error.message` property of response if it is an error response.
"""

RPC_JSONRPC_REQUEST_ID: Final = "rpc.jsonrpc.request_id"
"""
`id` property of request or response. Since protocol allows id to be int, string, `null` or missing (for notifications), value is expected to be cast to string for simplicity. Use empty string in case of `null` value. Omit entirely if this is a notification.
"""

RPC_JSONRPC_VERSION: Final = "rpc.jsonrpc.version"
"""
Protocol version as in `jsonrpc` property of request/response. Since JSON-RPC 1.0 doesn't specify this, the value can be omitted.
"""

"""
Compressed size of the message in bytes.
"""

MUST be calculated as two different counters starting from `1` one for sent messages and one for received message.
Note: This way we guarantee that the values will be consistent between different implementations.

Whether this is a received or sent message.

Uncompressed size of the message in bytes.
"""

RPC_METHOD: Final = "rpc.method"
"""
The name of the (logical) method being called, must be equal to the $method part in the span name.
Note: This is the logical name of the method from the RPC interface perspective, which can be different from the name of any implementing method/function. The `code.function.name` attribute may be used to store the latter (e.g., method actually executing the call on the server side, RPC client stub method on the client side).
"""

RPC_SERVICE: Final = "rpc.service"
"""
The full (logical) name of the service being called, including its package name, if applicable.
Note: This is the logical name of the service from the RPC interface perspective, which can be different from the name of any implementing class.

A string identifying the remoting system. See below for a list of well-known identifiers.
