Expand description

Support extended traits of jsonpath, css selector, and xpath

Required Methods§

Source

fn jsonpath(self) -> impl Future<Output = Result<Json>>

Use jsonpath to select the response body

Source

fn json_with_path_to_err<T: DeserializeOwned>( self, ) -> impl Future<Output = Result<T>>

works with any existing Serde Deserializer and exposes the chain of field names leading to the error.

Source

fn css_selector(self) -> impl Future<Output = Result<Html>>

Use CSS selector to select the response body

Source

fn xpath(self) -> impl Future<Output = Result<XHtml>>

Use XPath to select the response body

Source

fn html(self) -> impl Future<Output = Result<String>>

If there is no Encoding method in the Content-Type of the response header, try to read the meta information in the HTML to obtain the encoding. eg:

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
