Struct ArgumentsParser 

pub struct ArgumentsParser<'arg, I> { /* private fields */ }

An ArgumentsParser is the main entry point into debate_parser. It parses arguments in each call to next_arg, sending those arguments to the given Visitor. It handles distinguishing flags, options, and positionals; logic related to how flags get their argument values, and the --

debate-parser operates entirely on borrowed data, because we assume that command-line arguments can be loaded early on in main and then handled in a borrowed form for the rest of the program. The ubiquitous 'arg lifetime refers to this borrowed command line data.

Implementations

impl<'arg, I> ArgumentsParser<'arg, I>

where I: Iterator<Item = &'arg [u8]>,

pub fn new(args: impl IntoIterator<IntoIter = I>) -> Self

Create a new ArgumentsParser from an iterator of byte slices, where each byte slice is a single argument received from the command line. This list should exclude the name of the program, which is commonly passed as the first argument in the list.

pub fn new_from_slice( slice: &[impl AsBytes], ) -> ArgumentsParser<'_, impl Iterator<Item = &[u8]>>

pub fn next_arg<V>(&mut self, visitor: V) -> Option<V::Value>

where V: Visitor<'arg>,
