Struct graphul::extract::Host

pub struct Host(pub String);

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

impl Clone for Host

fn clone(&self) -> Host

Returns a copy 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<(), Error>

Formats the value using the given formatter.

impl<S> FromRequestParts<S> for Hostwhere 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.

fn from_request_parts<'life0, 'life1, 'async_trait>( parts: &'life0 mut Parts, _state: &'life1 S ) -> Pin<Box<dyn Future<Output = Result<Host, <Host as FromRequestParts<S>>::Rejection>> + Send + 'async_trait, Global>>where 'life0: 'async_trait, 'life1: 'async_trait, Host: 'async_trait,

Perform the extraction.
