Errors from envelope construction.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

RangeOutOfBounds

Fields

start: u32

end: u32

len: usize

InvalidUtf8

Fields

start: u32

end: u32

source: Utf8Error

EventTypeRangeTooLong

The event_type range length exceeds the wire-format cap.

Structurally rules out the only path that could otherwise hand EventType::from_validated_bytes an oversize slice on the read side, so the fast-path accessor is sound by construction.

Fields

actual: u32

max: usize

MetadataRangeTooLong

The metadata range length exceeds the wire-format cap.

Mirrors EventTypeRangeTooLong for metadata.

Fields

actual: u32

max: usize

MetadataRangeEmpty

Some(range) was passed where range is empty. The wire format reserves the absent sentinel (meta_len == u32::MAX) for “no metadata”; an empty range collides with the Bytes::slice(empty) STATIC_VTABLE orphan footgun and the value newtype invariant !Metadata::is_empty().

Value(ValueError)

Trait Implementations

impl Debug for EnvelopeError

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

Formats the value using the given formatter.

impl Display for EnvelopeError

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

Formats the value using the given formatter.

impl Error for EnvelopeError

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<EnvelopeError> for ForDecodeError

fn from(source: EnvelopeError) -> Self

Converts to this type from the input type.

impl<A, EncErr, DecErr> From<EnvelopeError> for StoreError<A, EncErr, DecErr>

fn from(source: EnvelopeError) -> Self

Converts to this type from the input type.

impl From<ValueError> for EnvelopeError

fn from(source: ValueError) -> Self

Converts to this type from the input type.
