Struct Logger 

pub struct Logger {
    pub config: LoggerConfig,
    /* private fields */
}

A high-performance logger utilizing a MPSC channel under the hood.

A logger is initialized with a LoggerConfig to set up different logging levels for stdout, file, and components. The logger spawns a thread that listens for LogEvents sent via an MPSC channel.

Fields

config: LoggerConfig

Initialization snapshot for logging levels and behavior.

Producer filters are derived into filter_policy at initialization; mutating this field after registration does not reload component/module filters.

Implementations

impl Logger

pub fn init_with_env( trader_id: TraderId, instance_id: UUID4, file_config: FileWriterConfig, ) -> Result<LogGuard>

Initializes the logger based on the NAUTILUS_LOG environment variable.

Errors

Returns an error if reading the environment variable or parsing the configuration fails.

pub fn init_with_config( trader_id: TraderId, instance_id: UUID4, config: LoggerConfig, file_config: FileWriterConfig, ) -> Result<LogGuard>

Initializes the logger with the given configuration.

Errors

Returns an error if the logger fails to register or initialize the background thread.
