ErrorCode

Enum ErrorCode 

Source
#[non_exhaustive]
pub enum ErrorCode { Normal, ProtocolError, InternalError, FlowControlError, StreamLimit, InvalidVersion, Timeout, Unknown(u32), }
Expand description

Wire-level error code, transmitted in GoAway frames as a u32.

Unknown codes coming from the peer are preserved as ErrorCode::Unknown so applications can still observe them.

Variants (Non-exhaustive)§

This enum is marked as 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.
§

Normal

Graceful shutdown initiated locally or remotely.

§

ProtocolError

Wire-format / framing violation.

§

InternalError

Internal bug in either side.

§

FlowControlError

Peer violated flow control (e.g. sent more bytes than advertised).

§

StreamLimit

Maximum concurrent streams would be exceeded.

§

InvalidVersion

Protocol version mismatch.

§

Timeout

Idle / keepalive timeout fired.

§

Unknown(u32)

Code not recognised by this version of the library.
