Struct LoggingConfig 

pub struct LoggingConfig {
    pub level: LevelFilter,
    pub format: LogFormat,
}

Logging configuration.

Controls the verbosity and format of log output. Logs are always written to stderr.

Fields

level: LevelFilter

Minimum log level to output.

Controls which log messages are emitted based on their severity. Messages at or above this level will be output. Valid levels in increasing severity: TRACE, DEBUG, INFO, WARN, ERROR, OFF.

The RUST_LOG environment variable provides more granular control per module if needed.

Important: Levels DEBUG and TRACE are very verbose and can impact performance; use only for debugging.

Default

INFO

Environment Variable

OS__LOGGING__LEVEL

Considerations

• TRACE and DEBUG can be very verbose and impact performance; use only for debugging
• INFO is appropriate for production
• WARN or ERROR can be used to reduce log volume in high-traffic systems

format: LogFormat

Log output format.

Determines how log messages are formatted. See LogFormat for available options and examples.

Default

Auto (pretty for TTY, simplified otherwise)

Environment Variable

OS__LOGGING__FORMAT
