Struct LogArgs 

pub struct LogArgs {
    pub verbose: u8,
    pub log_file: Option<PathBuf>,
    pub log_no_color: bool,
}

Logging configuration arguments.

Fields

verbose: u8

Increase logging verbosity (-v = error, -vv = warn, -vvv = info, -vvvv = debug, -vvvvv = trace)

log_file: Option<PathBuf>

Log file path. If specified, logs are written to this file instead of stderr.

log_no_color: bool

Disable colorful console logging. Only applies when logging to stderr (no –log.file).

Implementations

impl LogArgs

pub fn init(&self)

Initialize the tracing subscriber based on the logging configuration.

The log level is determined in the following order of precedence:

1. RUST_LOG environment variable (if set)
2. -v flags (increases from ERROR to WARN/INFO/DEBUG/TRACE)
3. Default is no logging (OFF)

Log target is only shown for DEBUG level and above. If --log.file is specified, logs are written to the file instead of stderr.

Trait Implementations

impl Args for LogArgs

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 LogArgs

fn clone(&self) -> LogArgs

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CommandFactory for LogArgs

fn command<'b>() -> Command

Build a Command that can instantiate Self.

fn command_for_update<'b>() -> Command

Build a Command that can update self.

impl Debug for LogArgs

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

Formats the value using the given formatter.

impl Default for LogArgs

fn default() -> LogArgs

Returns the “default value” for a type.

impl FromArgMatches for LogArgs

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>

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

Assign values from ArgMatches to self.

impl Parser for LogArgs

fn parse() -> Self

Parse from std::env::args_os(), exit on error.

fn try_parse() -> Result<Self, Error>

Parse from std::env::args_os(), return Err on error.
