Trait structopt::StructOpt
[−]
[src]
pub trait StructOpt { fn clap<'a, 'b>() -> App<'a, 'b>; fn from_clap(_: &ArgMatches) -> Self; fn from_args() -> Self
where
Self: Sized, { ... } fn from_iter<I>(iter: I) -> Self
where
Self: Sized,
I: IntoIterator,
I::Item: Into<OsString> + Clone, { ... } }
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(_: &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 where
Self: Sized,
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) -> Self where
Self: Sized,
I: IntoIterator,
I::Item: Into<OsString> + Clone,
Self: Sized,
I: IntoIterator,
I::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.
