Enum HandleDecodeError 

#[non_exhaustive]
pub enum HandleDecodeError {
    Truncated {
        needed: usize,
        at: usize,
        have: usize,

    },
    ParseField {
        field: &'static str,
        detail: String,
    },
}

Typed decode-failure classification. Mapped to EngineError::Validation { kind: Corruption, .. } at the backend boundary via the From impl.

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.

Truncated

Buffer shorter than required by the current read position.

Fields

needed: usize

at: usize

have: usize

TrailingBytes

Trailing bytes after the last expected field.

Fields

pos: usize

len: usize

BadWireVersion

v2 wire-version byte did not match a supported version.

Fields

got: u8

BadV1Version

v1-path version byte did not match the expected tag.

Fields

got: u8

BadBackendTag

v2 backend-tag byte did not map to a known BackendTag.

Fields

got: u8

InvalidUtf8

A length-prefixed string had invalid UTF-8.

Fields

field: &'static str

ParseField

A parsed id/field failed its own validation (e.g. ExecutionId::parse).

Fields

field: &'static str

detail: String

Trait Implementations

impl Clone for HandleDecodeError

fn clone(&self) -> HandleDecodeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HandleDecodeError

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

Formats the value using the given formatter.

impl Display for HandleDecodeError

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

Formats the value using the given formatter.

impl Error for HandleDecodeError

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<HandleDecodeError> for EngineError

fn from(err: HandleDecodeError) -> Self

Converts to this type from the input type.

impl PartialEq for HandleDecodeError

fn eq(&self, other: &HandleDecodeError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
