Enum NcsReadError 

pub enum NcsReadError {
    Header(NcsHeaderError),
    Opcode(UnknownNcsOpcode),
    AuxCode(UnknownNcsAuxCode),
    TruncatedInstruction {
        offset: usize,
        expected_extra: usize,
        actual_extra: usize,
    },
}

Errors returned while decoding a full NCS bytecode stream.

Variants

Header(NcsHeaderError)

Fixed header decode failed.

Opcode(UnknownNcsOpcode)

An opcode byte was unknown.

AuxCode(UnknownNcsAuxCode)

An auxcode byte was unknown.

TruncatedInstruction

One instruction payload was truncated.

Fields

offset: usize

Byte offset of the truncated instruction.

expected_extra: usize

Expected payload size after opcode and auxcode.

actual_extra: usize

Actual available payload bytes.

Trait Implementations

impl Clone for NcsReadError

fn clone(&self) -> NcsReadError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NcsReadError

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

Formats the value using the given formatter.

impl Display for NcsReadError

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

Formats the value using the given formatter.

impl Error for NcsReadError

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<NcsHeaderError> for NcsReadError

fn from(value: NcsHeaderError) -> Self

Converts to this type from the input type.

impl From<NcsReadError> for NcsAsmError

fn from(value: NcsReadError) -> Self

Converts to this type from the input type.

impl From<NcsReadError> for VmError

fn from(value: NcsReadError) -> Self

Converts to this type from the input type.

impl From<UnknownNcsAuxCode> for NcsReadError

fn from(value: UnknownNcsAuxCode) -> Self

Converts to this type from the input type.

impl From<UnknownNcsOpcode> for NcsReadError

fn from(value: UnknownNcsOpcode) -> Self

Converts to this type from the input type.

impl PartialEq for NcsReadError

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