Resource

endpoint

A logging endpoint.

resource endpoint;

F write

write: func(msg: list<u8>);

Writes a data to the given endpoint.

Each call to write with a non-empty message produces a single log event.

F open

open: func(name: string) -> result<endpoint, open-error>;

Tries to get an endpoint by name.

Currently, the conditions on an endpoint name are:

It must not be empty.
It must not contain newlines (\n) or colons (:).
It must not be stdout or stderr, which are reserved for debugging.

Names are case sensitive. Calling get-endpoint with a name that doesn't correspond to any logging endpoint available in your service will still return a usable endpoint, and writes to that endpoint will succeed. Refer to your service dashboard to diagnose missing log events.
