Available on crate feature integrity only.

HTTP integrity construction, parsing, or verification failure.

Variants

InvalidField(&'static str)

A Structured Field is malformed or has the wrong semantic type.

MissingComponent(String)

A field or derived component is unavailable in this message context.

InvalidComponent(String)

A component identifier or its parameters cannot be processed.

InvalidTargetUri

The message context lacks a valid, absolute HTTP(S) target URI.

DuplicateComponent

Covered components must be unique, regardless of parameter ordering.

DuplicateLabel

Reusing a signature label would make selection ambiguous.

ContentDigest

SHA-256 was absent, malformed, or did not match the message content.

Algorithm

An algorithm other than Ed25519 was requested or asserted.

Signature

Ed25519 verification failed.

Policy(&'static str)

A required profile constraint was not satisfied.

Limit

Integrity metadata exceeded the documented parsing limits.

FrameOrder

A frame appeared after trailers, or more than one trailer frame appeared.

TrailersUnavailable

Streaming trailers cannot be used with these HTTP semantics.

Random(String)

OS entropy could not be obtained.

Clock

The wall clock cannot be represented as a nonnegative UNIX timestamp.

Trait Implementations

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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 From<Error> for Error

fn from(_: Error) -> Self

Converts to this type from the input type.

impl<E> From<Error> for BodyError<E>

fn from(source: Error) -> Self

Converts to this type from the input type.
