Enum DecodeError 

pub enum DecodeError {
    UnknownOpcode {
        value: i64,
    },
    ReservedOpcode {
        value: i64,
    },
    NonZeroUnusedField {
        field: &'static str,
        value: i64,
    },
}

Why a word is not a valid instruction.

Variants

UnknownOpcode

Opcode is in the defined range but not assigned.

Fields

value: i64

The opcode field’s value.

ReservedOpcode

Opcode is negative - reserved for future extension.

Fields

value: i64

The opcode field’s value.

NonZeroUnusedField

A field the format does not use held a non-zero value. Rejected rather than ignored, so re-encoding a decoded word reproduces it exactly.

Fields

field: &'static str

Which field.

value: i64

What it held.

Trait Implementations

impl Clone for DecodeError

fn clone(&self) -> DecodeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DecodeError

impl Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

impl Eq for DecodeError

impl Error for DecodeError

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 PartialEq for DecodeError

fn eq(&self, other: &DecodeError) -> 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.
