Errors from the sending API.

Variants

UnknownStream

No such stream (never opened, or closed and forgotten).

StreamReset

The stream was reset.

StreamClosed

We already ended the stream.

HeadersAlreadySent

Final headers were already sent.

HeadersNotSent

Data or trailers before the headers.

InvalidHeader

A field name or value that HTTP/2 does not allow, or an invalid status.

StreamLimit

The peer’s SETTINGS_MAX_CONCURRENT_STREAMS is reached.

StreamIdsExhausted

No stream identifiers left: open a new connection.

GoingAway

The peer sent GOAWAY: no new streams.

ConnectionClosed

The connection is closed.

WrongRole

The call is for the other role (for example a client sending a response).

InvalidUpgradeSettings

An HTTP2-Settings value that is not valid base64url SETTINGS.

HeaderListTooLarge

The header block is larger than the peer’s SETTINGS_MAX_HEADER_LIST_SIZE; nothing was sent.

ConnectProtocolDisabled

An extended CONNECT before the server enabled it with SETTINGS_ENABLE_CONNECT_PROTOCOL (RFC 8441 §3); nothing was sent.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Error

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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

Returns the lower-level source of this error, if any.

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.

impl PartialEq for Error

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
