Struct LogSettings

pub struct LogSettings {
    pub tracing_level: String,
    pub pretty_log: Option<bool>,
    pub journald: Option<bool>,
}

Log related settings.

Description

This application outputs logs to a file by default. The file’s name and path is set via [LogSettings::log_output_file]. Output messages are append to the file if it exists previously. Use logrotate or any other application to avoid ending with an enormous log file.

Aside from that file, the application allows to output log messages to stdout as well, useful for debugging sessions. This feature is enabled via [LogSettings::enable_console_log].

Finally, the severity of the log messages to the console (when enabled) is also configurable, thus it is allowed to set different severity levels for the regular file log and the console log. This might be useful to avoid cluttering the console output with too much information that could be read from the logfile.

Fields

tracing_level: String

See tracing::Level. Accepted values are specified at LogSettings::get_verbosity_level.

pretty_log: Option<bool>

Enable console log output.

journald: Option<bool>

Is the application running by systemd? If so, log to journald.

Implementations

impl LogSettings

pub fn get_verbosity_level(&self) -> LevelFilter

Get the chosen verbosity level as a [LevelFilter] object.

Description

Translate the tracing level that is given via a configuration file into a [LevelFilter] object. Such object can be passed straight to a Subscriber to specify a filter for the log messages.

Accepted values:

• debug or dbg to set the verbiosity to DEBUG.
• info to set the verbosity to INFO.
• error or err to set the verbosity to ERROR.
• trace to set the verbosity to TRACE.
• warn or any other string to set the verbosity to WARN.
