Method add

option_parser/src/lib.rs:184–200

Registers a named option that requires a value (i.e. `key=value`). Option names must not contain `"`, `[`, `]`, `=`, or `,`. Returns `&mut Self` for chaining. # Panics Panics if the option name contains a forbidden character.

(&mut self, option: &str)

    /// Panics if the option name contains a forbidden character.
    pub fn add(&mut self, option: &str) -> &mut Self {
        // Check that option=value has balanced
        // quotes and brackets iff value does.
        assert!(
            !option.contains(['"', '[', ']', '=', ',']),
            "forbidden character in option name"
