Struct Path 

pub struct Path<D>(pub D);

An extractor that extracts data from the URL params.

The extractor is generic over a type that implements serde::de::DeserializeOwned.

Examples

use cot::html::Html;
use cot::request::extractors::{FromRequest, Path};
use cot::request::{Request, RequestExt};
use cot::router::{Route, Router};
use cot::test::TestRequestBuilder;

async fn my_handler(Path(my_param): Path<String>) -> Html {
    Html::new(format!("Hello {my_param}!"))
}

let router = Router::with_urls([Route::with_handler_and_name(
    "/{my_param}/",
    my_handler,
    "home",
)]);
let request = TestRequestBuilder::get("/world/")
    .router(router.clone())
    .build();

assert_eq!(
    router
        .handle(request)
        .await?
        .into_body()
        .into_bytes()
        .await?,
    "Hello world!"
);

Trait Implementations

impl<D: JsonSchema> ApiOperationPart for Path<D>

Available on crate feature openapi only.

fn modify_api_operation( operation: &mut Operation, route_context: &RouteContext<'_>, schema_generator: &mut SchemaGenerator, )

Modify the OpenAPI operation object.

impl<D: Clone> Clone for Path<D>

fn clone(&self) -> Path<D>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<D: Debug> Debug for Path<D>

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

Formats the value using the given formatter.

impl<D: DeserializeOwned> FromRequestHead for Path<D>

async fn from_request_head(head: &RequestHead) -> Result<Self>

Extracts data from the request head.

impl<D: Hash> Hash for Path<D>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<D: Ord> Ord for Path<D>

fn cmp(&self, other: &Path<D>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<D: PartialEq> PartialEq for Path<D>

fn eq(&self, other: &Path<D>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<D: PartialOrd> PartialOrd for Path<D>

fn partial_cmp(&self, other: &Path<D>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
