Struct axum::extract::Host

source · [−]

pub struct Host(pub String);

Expand description

Extractor that resolves the hostname of the request.

Hostname is resolved through the following, in order:

Forwarded header
X-Forwarded-Host header
Host header
request target / URI

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

source

impl Clone for Host

source

fn clone(&self) -> Host

Returns a copy of the value. Read more

1.0.0 · source

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

Performs copy-assignment from source. Read more

source

impl Debug for Host

source

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

Formats the value using the given formatter. Read more

source

impl FromRequest for Host where
B: Send,

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. Read more

source

fn from_request<'life0, 'async_trait>(
 req: &'life0 mut RequestParts
) -> Pin<Box<dyn Future<Output = Result<Self, Self::Rejection>> + Send + 'async_trait>> where
 'life0: 'async_trait,
 Self: 'async_trait,

Perform the extraction.
