4//! Log-output capability trait.
5//!
6//! Lets the trace pipeline emit already-encoded log-exporter output to the
7//! platform's log sink. On native targets this writes to process stdout; a wasm
8//! consumer implements it by handing the bytes to the host (e.g. JavaScript),
9//! since wasm cannot write to stdout directly.
