Struct gumdrop::Parser

pub struct Parser<'a, S: 'a> { /* fields omitted */ }

Parses options from a series of &str-like values.

Methods

impl<'a, S: 'a + AsRef<str>> Parser<'a, S>

fn new(args: &'a [S], style: ParsingStyle) -> Parser<'a, S>

Returns a new parser for the given series of arguments.

The given slice should not contain the program name as its first element.

fn next_opt(&mut self) -> Option<Opt<'a>>

Returns the next option or None if no options remain.

If the previous option had an explicit argument, e.g. --option=argument, which was not consumed by a call to next_arg(), an error will be returned indicating that the argument was ignored.

fn next_arg(&mut self) -> Option<&'a str>

Returns the next argument to an option or None if none remain.

Trait Implementations

impl<'a, S: 'a> Clone for Parser<'a, S>

fn clone(&self) -> Parser<'a, S>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
