Struct Args 

pub struct Args<S: ?Sized>(/* private fields */);

Remaining unparsed arguments.

Implementations

impl<S: Source + ?Sized> Args<S>

pub fn parse<T: FromArgs>(&mut self, field: Ident) -> FromArgsResult<T>

Parse the value of a field.

This method is like FromArgs::from_args except that it attaches the field context to a returned error.

pub fn branch<T, const LEN: usize>( &mut self, branches: [(&'static str, fn(args: &mut Args<S>) -> FromArgsResult<T>); LEN], ) -> FromArgsResult<T>

Parse the rest of args with the parser tupled with the string that matches the first arg.

This method will return an error if the first arg does not match any of the variants or if parsing the rest of the args returns an error.

pub fn as_iter<T: FromArgs>(&mut self) -> AsIter<'_, S, T>

Create an iterator that repeatedly parses Option<T> from self.

This iterator is like parse in that it attaches the iteration index context to a returned error.

Trait Implementations

impl<S: Clone + ?Sized> Clone for Args<S>

fn clone(&self) -> Args<S>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S: Debug + ?Sized> Debug for Args<S>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
