Enum DecodeError 

pub enum DecodeError {
    UnexpectedEof,
    UnknownOpcode(u8),
    UnknownTag(u8),
    UnknownFieldId(u8),
    InvalidBool(u8),
    InvalidUtf8,
}

A typed decode failure. No variant is reachable by a valid buffer; every one corresponds to a specific malformation at the FFI trust boundary.

Variants

UnexpectedEof

The buffer ended in the middle of a record/primitive. Carries the number of bytes that were still required.

UnknownOpcode(u8)

An opcode byte that does not map to any Op variant.

UnknownTag(u8)

An enum tag byte (Kind, Dim, AttrValue, a Style sub-enum, …) out of range for its position.

UnknownFieldId(u8)

A Style field id with no assigned meaning.

InvalidBool(u8)

A bool byte that was neither 0x00 nor 0x01.

InvalidUtf8

A length-prefixed string whose bytes were not valid UTF-8.

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

Formats the value using the given formatter.

impl Display for DecodeError

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

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.
