Struct spirit_log::Opts

pub struct Opts { /* fields omitted */ }

A fragment for command line options.

By flattening this into the top-level StructOpt structure, you get the -l and -L command line options. The -l (--log) sets the global logging level for stderr. The -L accepts pairs (eg. -L spirit=TRACE) specifying levels for specific logging targets.

If used, the logging will be sent to stderr.

Trait Implementations

impl Clone for Opts

fn clone(&self) -> Opts

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Opts

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

Formats the value using the given formatter.

impl StructOpt for Opts

fn clap<'a, 'b>() -> App<'a, 'b>

Returns the corresponding clap::App.

fn from_clap(matches: &ArgMatches) -> Self

Creates the struct from clap::ArgMatches. It cannot fail with a parameter generated by clap by construction.

fn from_args() -> Self

Gets the struct from the command line arguments. Print the error message and quit the program in case of failure.

fn from_iter<I>(iter: I) -> Self where
    I: IntoIterator,
    <I as IntoIterator>::Item: Into<OsString>,
    <I as IntoIterator>::Item: Clone, 

Gets the struct from any iterator such as a Vec of your making. Print the error message and quit the program in case of failure.

fn from_iter_safe<I>(iter: I) -> Result<Self, Error> where
    I: IntoIterator,
    <I as IntoIterator>::Item: Into<OsString>,
    <I as IntoIterator>::Item: Clone, 

Gets the struct from any iterator such as a Vec of your making.
