[−][src]Trait md_inc::StructOpt
A struct that is converted from command line arguments.
Required methods
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.
Provided methods
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,
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.
NOTE: The first argument will be parsed as the binary name unless
AppSettings::NoBinaryName
has been used.
fn from_iter_safe<I>(iter: I) -> Result<Self, Error> where
I: IntoIterator,
<I as IntoIterator>::Item: Into<OsString>,
<I as IntoIterator>::Item: Clone,
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.
Returns a clap::Error
in case of failure. This does not exit in the
case of --help
or --version
, to achieve the same behavior as
from_iter()
you must call .exit()
on the error value.
NOTE: The first argument will be parsed as the binary name unless
AppSettings::NoBinaryName
has been used.
