pub const DEFAULT_LOG_FILTER: &str = "info,hyper=warn,hyper_util=warn,h2=warn,mio=warn";Expand description
Filter used when RUST_LOG is unset.
info for this project’s own crates, and the HTTP stack’s internals turned
down. hyper and h2 narrate every frame at DEBUG; leaving them on turns
the provisioning log – the thing this server exists to show – into a
minority of the output.
tower is deliberately not silenced here even though it is noisy in the
same way. EnvFilter matches a target by string prefix, so a tower=warn
directive also silences tower_http::trace, which is where this crate’s
request log comes from.
