Struct quicli::prelude::Verbosity

pub struct Verbosity { /* private fields */ }

Easily add a --verbose flag to CLIs using Structopt

Examples

extern crate clap_verbosity_flag;
#[macro_use] extern crate structopt;

use structopt::StructOpt;
use clap_verbosity_flag::Verbosity;

/// Le CLI
#[derive(Debug, StructOpt)]
struct Cli {
    #[structopt(flatten)]
    verbose: Verbosity,
}

Implementations

impl Verbosity

pub fn log_level(&self) -> Level

Get the log level.

pub fn setup_env_logger(&self, own_pkg_name: &str) -> Result<(), Error>

Initialize env_logger and set the log level for the given package.

All other modules default to printing warnings.

Trait Implementations

impl Clone for Verbosity

fn clone(&self) -> Verbosity

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Verbosity

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

Formats the value using the given formatter.

impl Display for Verbosity

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

Formats the value using the given formatter.

impl StructOpt for Verbosity

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

Returns the corresponding clap::App.

fn from_clap(matches: &ArgMatches<'_>) -> Verbosity

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

fn from_args() -> Selfwhere
    Self: Sized,

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) -> Selfwhere
    Self: Sized,
    I: IntoIterator,
    <I as IntoIterator>::Item: Into<OsString> + 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
    Self: Sized,
    I: IntoIterator,
    <I as IntoIterator>::Item: Into<OsString> + Clone,

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