Enum fastly::http::request::SendErrorCause

#[non_exhaustive]
pub enum SendErrorCause {
    Invalid,
    Incomplete,
    InvalidStatus,
    HeadTooLarge,
    BufferSize(BufferSizeError),
    Generic(Error),
}

The reason that a request sent to a backend failed.

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.

Invalid

The backend responded with something that was not valid HTTP.

Incomplete

The backend responded, but we didn’t get a complete response before the connection closed.

InvalidStatus

The backend responded with an invalid HTTP code.

HeadTooLarge

The backend responded with a HTTP message head that was too large.

BufferSize(BufferSizeError)

Ran out of buffer space for part of the response.

See the limits module to adjust the maximum buffer sizes.

Generic(Error)

All other errors.

impl Error for SendErrorCause

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()
