Trait rt_format::argument::PositionalArguments

pub trait PositionalArguments<'v, V> where
    V: 'v + FormatArgument, {
    type Iter: Iterator<Item = &'v V>;
    fn get(&self, index: usize) -> Option<&V>;
    fn iter(&'v self) -> Self::Iter;
}

A type that provides a list of arguments, randomly accessible by their position.

Associated Types

type Iter: Iterator<Item = &'v V>

The type of the iterator that can be used to iterate over arguments.

Required methods

fn get(&self, index: usize) -> Option<&V>

Returns a reference to the argument at the given index, if any.

fn iter(&'v self) -> Self::Iter

Creates an iterator over the arguments.
