Struct bdrck_params::argument::Argument

pub struct Argument {
    pub name: String,
    pub help: String,
    pub default_value: Optional<Vec<String>>,
}

An argument is a positional parameter. It must come after any Options the command supports, and can have a default value if it is not specified by the user explicitly.

The final Argument for a Command can be variadic (that is, it can accept more than one value), but whether or not this is the case is a property of the Command, not of the Argument (because the Argument only stores a description of the argument, not its final value).

Fields

name: String

help: String

default_value: Optional<Vec<String>>

Methods

fn new(name: &str, help: &str, default_value: Optional<Vec<String>>) -> Argument
