Enum DntError 

pub enum DntError {
    InvalidFormat,
    UnsupportedVersion,
    PayloadTooLarge,
    InvalidFlags,
    ContextMismatch,
    KeyUnavailable,
    AuthenticationFailed,
    CodecUnavailable,
    CodecFailed,
    Io,
}

Controlled DNT failures.

Variants

InvalidFormat

The bytes do not contain a structurally valid DNT envelope.

UnsupportedVersion

The envelope version is newer or otherwise unsupported.

PayloadTooLarge

The configured maximum payload size would be exceeded.

InvalidFlags

The envelope contains an impossible or unsupported flag combination.

ContextMismatch

The envelope is not bound to the expected context.

KeyUnavailable

The key provider could not return usable material.

AuthenticationFailed

AEAD authentication failed.

CodecUnavailable

The codec identifier is unknown or incompatible.

CodecFailed

Encoding or decoding failed without exposing payload material.

Io

Filesystem persistence failed.

Trait Implementations

impl Clone for DntError

fn clone(&self) -> DntError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DntError

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

Formats the value using the given formatter.

impl Display for DntError

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

Formats the value using the given formatter.

impl Eq for DntError

impl Error for DntError

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.

fn from(_: CodecError) -> Self

Converts to this type from the input type.

impl From<DntKeyError> for DntError

fn from(value: DntKeyError) -> Self
