Struct Params 

pub struct Params(/* private fields */);

Captured path parameters, in the order the route captured them.

Order matters: Path<(A, B)> destructures positionally, so a HashMap would make /users/{id}/posts/{post} ambiguous.

Implementations

impl Params

pub fn new() -> Self

An empty set.

pub fn insert(&mut self, name: String, value: String)

Add or replace name.

pub fn remove(&mut self, name: &str)

Drop name, if present.

pub fn get(&self, name: &str) -> Option<&str>

The value for name.

pub fn iter(&self) -> impl Iterator<Item = (&str, &str)>

Pairs in capture order.

pub fn contains_key(&self, name: &str) -> bool

Whether name was captured.

pub fn nth(&self, index: usize) -> Option<&str>

The value at index, in capture order.

pub fn len(&self) -> usize

How many were captured.

pub fn is_empty(&self) -> bool

Whether none were captured.

pub fn clear(&mut self)

Discard every capture.
