Struct Args

pub struct Args<'k> { /* private fields */ }

This is an easy way to build an argument mapping for the template application method

The key must be a &str while the value can be any std::fmt::Display trait object

note The keys are unique, duplicates will be replaced by the last one

let args = Args::new()
    .with("key1", &false)
    .with("key2", &"message")
    .with("key3", &41)
    .with("key3", &42);

Implementations

impl<'k> Args<'k>

pub fn new() -> Self

Create a new Args builder

pub fn len(&self) -> usize

Length of the args

pub fn is_empty(&self) -> bool

Whether the args is empty

pub fn with(self, key: impl Into<Cow<'k, str>>, val: impl Display) -> Self

Maps a key to a type that implements std::fmt::Display

pub fn iter(&self) -> impl Iterator<Item = (&Cow<'k, str>, &String)> + '_

Trait Implementations

impl<'k> Clone for Args<'k>

fn clone(&self) -> Args<'k>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'k> Default for Args<'k>

fn default() -> Args<'k>

Returns the “default value” for a type.

impl<'k, K, V> FromIterator<(K, V)> for Args<'k>

where K: Into<Cow<'k, str>>, V: Display,

fn from_iter<T: IntoIterator<Item = (K, V)>>(iter: T) -> Self

Creates a value from an iterator.

impl<'k> IntoIterator for Args<'k>

type Item = (Cow<'k, str>, String)

The type of the elements being iterated over.

type IntoIter = IntoIter<Cow<'k, str>, String>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
