Expand description

A builder to construct the properties of a Request.

Implementations

source

impl RequestBuilder

source

pub fn query<T: Serialize + ?Sized>(self, query: &T) -> RequestBuilder

Modify the query string of the URL.

Modifies the URL of this request, adding the parameters provided. This method appends and does not overwrite. This means that it can be called multiple times and that existing query parameters are not overwritten if the same key is used. The key will simply show up twice in the query string. Calling .query([("foo", "a"), ("foo", "b")]) gives "foo=a&foo=b".

Note

This method does not support serializing a single key-value pair. Instead of using .query(("key", "val")), use a sequence, such as .query(&[("key", "val")]). It’s also possible to serialize structs and maps into a key-value pair.

Errors

This method will fail if the object you provide cannot be serialized into a query string.

source

pub fn form<T: Serialize + ?Sized>(self, form: &T) -> RequestBuilder

Send a form body.

Sets the body to the url encoded serialization of the passed value, and also sets the Content-Type: application/x-www-form-urlencoded header.

Errors

This method fails if the passed value cannot be serialized into url encoded format

source

pub async fn send(self) -> Result<Response>

Constructs the Request and sends it to the target URL, returning a future Response.

    .body("from a &str!");
let clone = builder.try_clone();
assert!(clone.is_some());
