CapsuleError

rama::http::datagram::capsule

Enum CapsuleError 

pub enum CapsuleError {
    TooLarge {
        ty: CapsuleType,
        length: u64,
    },
    Truncated,
    InputNotDrained,
}
Available on crate features http and std only.
Expand description

A Capsule Protocol violation. The data stream must be treated as a malformed or incomplete message (RFC 9297 §3.3).

Variants§

§

TooLarge

A registered control capsule exceeded CapsuleConfig::max_capsule_size.

Fields

§ty: CapsuleType

The capsule type.

§length: u64

The advertised value length.

§

Truncated

The data stream ended inside a capsule.

§

InputNotDrained

The previous input has not been drained with CapsuleDecoder::poll. This is a local usage error, not a peer violation.
