Struct LogArgs

pub struct LogArgs {
    pub log: Vec<Option<LogDestinationConfig>>,
}

Fields

log: Vec<Option<LogDestinationConfig>>

Log definition consisting of an optional log level filter, and a log destination. You can define this argument multiple times for multiple log destinations.

Logging can be disabled with --log none. If combined with other log definitions, those will take precedence and logging will not be disabled.

The argument can be combined with a level filter to only log messages of a certain level or higher to that destination.

Format: destination | level_filter:destination

• level_filter = “ERROR” | “WARN” | “INFO” | “DEBUG” | “TRACE”
• destination = “stderr” | “syslog” | “file:path” | “none”

Examples:

• --log syslog
• --log stderr
• --log file:/path/to/file
• --log INFO:stderr
• --log DEBUG:file:/path/to/file
• --log TRACE:syslog
• --log none

Implementations

impl LogArgs

pub fn or_default(&self, default: LoggingConfig) -> LoggingConfig

Build the LoggingConfig defined by the command line arguments from LogArgs. If no --log argument is given, the default config is returned.

Trait Implementations

impl Args for LogArgs
