Function go_flag::parse

pub fn parse<'a, T, F>(f: F) -> Vec<T> where
    T: FlagValue,
    F: FnOnce(&mut FlagSet<'a>), 

Parses the command-line arguments into flags.

Flags are registered in the given closure.

Returns

Returns the list of positional arguments (remaining arguments).

Positional arguments can also be parsed. You'll typically need Vec<String>, Vec<OsString> or Vec<PathBuf>.

Exits

It exits if the command-line arguments contain invalid flags.

Outputs

It prints errors and warnings to the standard error stream (stderr).

Example

let mut force = false;
let mut lines = 10_i32;
let args: Vec<String> = go_flag::parse(|flags| {
    flags.add_flag("f", &mut force);
    flags.add_flag("lines", &mut lines);
});
