Struct ReopenHandle 

pub struct ReopenHandle { /* private fields */ }

Token returned by build_logs_layer proving the SIGHUP log-reopen state has been initialised.

The token is zero-sized; its sole purpose is to make the “build the fmt layer, then install it as a global” handshake type-checked: callers cannot call reopen_on_sighup before the writer state has been wired, because they cannot construct a ReopenHandle without first calling build_logs_layer or one of its convenience wrappers.

Examples

use dynomite::core::log::{build_logs_layer, LogConfig, LogFormat, LOG_NOTICE};
// Building the layer also populates the SIGHUP-reopen state.
// The handle below is the proof of that wiring.
// (The example does not install the layer as a global so it
// can run side-by-side with the rest of the doctest suite.)
let cfg = LogConfig::new(LOG_NOTICE, None, LogFormat::Default);
let _ = build_logs_layer(&cfg);
