Main error type

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.

InvalidMachineMode

Invalid machine mode

InvalidStackWidth

Invalid stack width

DecodeFailed(DecodeError)

Failed to decode instruction

EncodeFailed(EncodeError)

Encoding failed

IncompleteInstruction

Incomplete instruction (need more bytes)

Fields

needed: usize

How many more bytes are needed

InsufficientBytes

Not enough bytes to decode

InstructionTooLong

Instruction exceeds maximum length (15 bytes)

InvalidEncoding

Invalid instruction encoding

BufferTooSmall

Buffer too small

InvalidOperand

Invalid operand

NotYetImplemented(&'static str)

Feature not implemented yet

UndefinedInstruction

Undefined or reserved instruction

Fields

opcode: u8

The opcode byte that caused the error

reason: UndefinedReason

Optional description of why it’s undefined

InvalidPrefixCombination

Invalid prefix combination

Fields

prefixes: &'static str

The conflicting prefixes

EvexEncodingError

EVEX encoding error (AVX-512 specific)

Fields

kind: EvexErrorKind

Specific EVEX error type

ModeNotSupported

Instruction not supported in current mode

Fields

mode: &'static str

The machine mode

feature: &'static str

The instruction or feature

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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

Formats the value using the given formatter.

impl PartialEq for Error

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

impl Eq for Error

impl StructuralPartialEq for Error
