Failure to semantically validate a decoded HTTP/3 field section.

field_index values identify decoded fields in wire order. They are not byte offsets because QPACK decoding does not retain a field’s encoded wire offset.

Variants

FieldSectionSizeOverflow

Adding a decoded field’s RFC 9114 size contribution overflowed u64.

Fields

field_index: usize

Index of the field whose contribution overflowed.

InvalidFieldName

A regular field name is empty or not an HTTP token.

Fields

field_index: usize

Index of the invalid field.

UppercaseFieldName

A regular field name contains an uppercase ASCII byte.

Fields

field_index: usize

Index of the invalid field.

InvalidFieldValue

A field value contains invalid HTTP field-content or leading/trailing whitespace.

Fields

field_index: usize

Index of the invalid field.

PseudoFieldAfterRegular

A pseudo-field follows a regular field.

Fields

field_index: usize

Index of the misplaced pseudo-field.

PseudoFieldInTrailers

A trailer section contains a pseudo-field.

Fields

field_index: usize

Index of the forbidden pseudo-field.

InvalidPseudoField

A pseudo-field is unknown or forbidden for this section context.

Fields

field_index: usize

Index of the invalid pseudo-field.

DuplicatePseudoField

A pseudo-field repeats an earlier pseudo-field.

Fields

field_index: usize

Index of the repeated pseudo-field.

MissingPseudoField

A required pseudo-field is absent.

Fields

name: &'static [u8]

Name of the missing pseudo-field.

ConnectionSpecificField

A connection-specific field is forbidden in HTTP/3.

Fields

field_index: usize

Index of the forbidden field.

InvalidTe

A te field is forbidden here or does not contain only trailers values.

Fields

field_index: usize

Index of the invalid field.

DuplicateHost

A host field repeats an earlier Host field.

Fields

field_index: usize

Index of the repeated Host field.

MissingAuthorityOrHost

A request has neither a nonempty :authority nor a nonempty Host field.

InvalidAuthority

A :authority value is invalid for the request form.

Fields

field_index: usize

Index of the invalid :authority field.

InvalidHost

A Host field is empty.

Fields

field_index: usize

Index of the invalid Host field.

AuthorityHostMismatch

:authority and Host are both present but differ.

Fields

authority_field_index: usize

Index of the :authority field.

host_field_index: usize

Index of the Host field.

InvalidMethod

The :method pseudo-field is empty or not an HTTP token.

Fields

field_index: usize

Index of the invalid :method field.

InvalidScheme

The :scheme pseudo-field is empty or malformed.

Fields

field_index: usize

Index of the invalid :scheme field.

InvalidPath

The :path pseudo-field is empty or invalid for an HTTP scheme.

Fields

field_index: usize

Index of the invalid :path field.

InvalidProtocol

The :protocol pseudo-field is disabled, malformed, or not paired with CONNECT.

Fields

field_index: usize

Index of the invalid :protocol field.

InvalidConnectPseudoFields

An ordinary CONNECT request contains :scheme or :path.

Fields

field_index: usize

Index of the first forbidden pseudo-field.

InvalidStatus

The :status pseudo-field is malformed, forbidden, or outside the accepted range.

Fields

field_index: usize

Index of the invalid :status field.

Implementations
