Function abstutil::logger::setup[][src]

pub fn setup()

On native: uses env_log

You can adjust the log level without recompiling with the RUST_LOG env variable.

RUST_LOG=debug cargo run --bin game

This can be done on a per lib basis:

RUST_LOG=my_lib=debug cargo run --bin game

Or a module-by-module basis:

RUST_LOG=my_lib::module=debug cargo run --bin game

You can mix and match:

# error logging by default, except the foo:bar module at debug level
# and the entire baz crate at info level
RUST_LOG=error,foo::bar=debug,baz=info cargo run --bin game

For some special cases, you might want to use regex matching by specifying a pattern with the “/”:

# only log once every 10k
RUST_LOG="fast_paths=debug/contracted node [0-9]+0000 " mike import_la

On web: uses console_log
