Enum HttpFetchError 

#[non_exhaustive]
pub enum HttpFetchError {
    Request {
        source: Error,
    },
    Status {
        status: StatusCode,
    },
    Body {
        source: Error,
    },
}

Transport-layer failure exposed by HttpFetcher.

HttpFetchError is what the boxed source of LoaderError::Fetch carries when produced by this crate. Downstream code that needs the structured detail (e.g. a status-code-specific retry) can downcast via std::error::Error::source and downcast_ref::<HttpFetchError>().

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Request

The underlying request could not be dispatched: DNS lookup failed, the connection was refused, the request timed out, etc.

Fields

source: Error

Status

The server returned a non-success status code.

Fields

status: StatusCode

Body

The response headers came back fine but the body could not be read.

Fields

source: Error

Trait Implementations

impl Debug for HttpFetchError

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
