Struct MatchedHost 

pub struct MatchedHost {
    pub subdomain: String,
    pub pattern: String,
}

Information about a wildcard host match.

Inserted into request extensions when a request matches a wildcard pattern (e.g. *.acme.com). Not present for exact or fallback matches.

Use Option<MatchedHost> for handlers that serve both exact and wildcard routes.

Example

async fn handler(matched: MatchedHost) -> impl IntoResponse {
    format!("subdomain: {}", matched.subdomain)
}

Fields

subdomain: String

The subdomain that matched (e.g. "tenant1" from "tenant1.acme.com").

pattern: String

The wildcard pattern that matched (e.g. "*.acme.com").

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

Perform the extraction.

impl<S> OptionalFromRequestParts<S> for MatchedHost

where S: Send + Sync,

type Rejection = Error

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.
