Struct Host 

pub struct Host(pub String);

👎Deprecated: will be removed in the next version; see https://github.com/tokio-rs/axum/issues/3442

Extractor that resolves the host of the request.

Host is resolved through the following, in order:

• Forwarded header
• X-Forwarded-Host header
• Host header
• Authority of the request URI

See https://www.rfc-editor.org/rfc/rfc9110.html#name-host-and-authority for the definition of host.

Note that user agents can set X-Forwarded-Host and Host headers to arbitrary values so make sure to validate them to avoid security issues.

Trait Implementations

impl Clone for Host

fn clone(&self) -> Host

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Host

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

Formats the value using the given formatter.

impl<S> FromRequestParts<S> for Host

where S: Send + Sync,

type Rejection = HostRejection

If the extractor fails it’ll use this “rejection” type. A rejection is a kind of error that can be converted into a response.

async fn from_request_parts( parts: &mut Parts, _state: &S, ) -> Result<Self, Self::Rejection>

Perform the extraction.

impl<S> OptionalFromRequestParts<S> for Host

where S: Send + Sync,

type Rejection = Infallible

If the extractor fails, it will use this “rejection” type.

async fn from_request_parts( parts: &mut Parts, _state: &S, ) -> Result<Option<Self>, Self::Rejection>

Perform the extraction.
