Struct LoggingArgs 

pub struct LoggingArgs {
    pub log_file: Option<PathBuf>,
    pub log_level: String,
}

Shared logging/tracing arguments available to all commands.

Language crates and command structs flatten this to get consistent --log-file and --log-level flags.

Fields

log_file: Option<PathBuf>

Path to a log file for debug/trace output. When set, all tracing events at the configured level are written here.

log_level: String

Log level filter (trace, debug, info, warn, error). Controls file output verbosity. Stderr progress display is always shown.

Trait Implementations

impl Args for LoggingArgs

fn group_id() -> Option<Id>

Report the ArgGroup::id for this set of arguments

fn augment_args<'b>(__clap_app: Command) -> Command

Append to Command so it can instantiate Self via FromArgMatches::from_arg_matches_mut

fn augment_args_for_update<'b>(__clap_app: Command) -> Command

Append to Command so it can instantiate self via FromArgMatches::update_from_arg_matches_mut

impl Clone for LoggingArgs

fn clone(&self) -> LoggingArgs

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LoggingArgs

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromArgMatches for LoggingArgs

fn from_arg_matches(__clap_arg_matches: &ArgMatches) -> Result<Self, Error>

Instantiate Self from ArgMatches, parsing the arguments as needed.

fn from_arg_matches_mut( __clap_arg_matches: &mut ArgMatches, ) -> Result<Self, Error>

Instantiate Self from ArgMatches, parsing the arguments as needed.

fn update_from_arg_matches( &mut self, __clap_arg_matches: &ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.

fn update_from_arg_matches_mut( &mut self, __clap_arg_matches: &mut ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.
