Struct ArgumentBuilder 

pub struct ArgumentBuilder<'a> { /* private fields */ }

A temporary builder object for configuring arguments.

This struct is returned by Parser::add_flag, add_option, and add_positional and allows for chaining configuration methods like .with_short_name() or .required().

Implementations

impl<'a> ArgumentBuilder<'a>

pub fn with_help(self, help_text: &str) -> Self

Adds a help message to the argument.

pub fn with_short_name(self, short_name: char) -> Self

Adds a short name (e.g., ‘-s’) to the argument.

pub fn required(self) -> Self

Marks the argument as required.

The parser will return an error if this argument is not provided.
