Error type for decoding binary IPC messages.

Variants

MessageTooShort

The message is too short (less than 12 bytes for header)

Fields

expected: usize

actual: usize

U8BufferEmpty

The u8 buffer is empty when trying to read

U16BufferEmpty

The u16 buffer is empty when trying to read

U32BufferEmpty

The u32 buffer is empty when trying to read

StringBufferTooShort

The string buffer doesn’t have enough bytes

Fields

expected: usize

actual: usize

InvalidUtf8

Invalid UTF-8 in string buffer

Fields

position: usize

InvalidMessageType

Invalid message type byte

Fields

value: u8

InvalidHeaderOffsets

Header offsets are invalid (e.g., overlapping or out of bounds)

Fields

u16_offset: u32

u8_offset: u32

str_offset: u32

total_len: usize

Custom(String)

Generic decode failure with context

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 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 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 From<DecodeError> for String

fn from(err: DecodeError) -> String

Converts to this type from the input type.

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.
