Failure while accounting for HTTP message content and Content-Length.

Local operation sequencing and tunnel handoff failures have no HTTP/3 peer error code. The remaining variants describe peer message-content violations.

Variants

InvalidContentLength

A Content-Length list member is empty or not an ASCII decimal number.

Fields

field_index: usize

Decoded field index in wire order.

member_index: usize

Comma-separated member index within the field value.

ContentLengthOverflow

A Content-Length list member overflows u64.

Fields

field_index: usize

Decoded field index in wire order.

member_index: usize

Comma-separated member index within the field value.

ConflictingContentLength

A Content-Length list member differs from the earlier normalized value.

Fields

field_index: usize

Decoded field index in wire order.

member_index: usize

Comma-separated member index within the field value.

expected: u64

Earlier normalized Content-Length.

actual: u64

Conflicting normalized Content-Length.

ContentLengthInTrailers

A trailer field section contains Content-Length.

Fields

field_index: usize

Decoded trailer field index in wire order.

ProhibitedContentLength

Content-Length is forbidden for this message form.

Fields

field_index: usize

Decoded field index in wire order.

UnexpectedHeaderSection

A validated header section was supplied at the wrong content-accounting operation.

Fields

expected: Http3ContentOperation

Operation expected by content accounting.

actual: Http3HeadersKind

Validated role carried by the supplied section.

OperationNotReady

A local content-accounting operation cannot proceed in the current message phase.

Fields

operation: Http3ContentOperation

Operation that cannot proceed.

ContentNotAllowed

DATA is forbidden because this message form has no HTTP content.

Fields

data_length: usize

Forbidden DATA payload length.

DataLengthNotRepresentable

A DATA payload length cannot be represented as u64.

Fields

length: usize

DATA payload length.

ReceivedLengthOverflow

Adding a DATA payload length overflows cumulative received length.

Fields

received_length: u64

Cumulative length before the DATA frame.

frame_length: u64

DATA payload length after conversion to u64.

ContentLengthMismatch

Received HTTP content does not equal the declared Content-Length.

Fields

declared: u64

Declared normalized Content-Length.

received: u64

Received HTTP content length.

NotHttpMessageContent

A caller supplied an HTTP-content operation after CONNECT tunnel handoff.

IncompleteMessage

The message ended before required initial or final headers were accepted.

Implementations

impl Http3MessageContentError

pub const fn error_code(self) -> Option<Http3ErrorCode>

Returns the HTTP/3 peer error code when this failure is peer-caused.

Trait Implementations

impl Clone for Http3MessageContentError

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 Http3MessageContentError

impl Debug for Http3MessageContentError

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

impl Eq for Http3MessageContentError

impl Error for Http3MessageContentError

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
