Enum DecodeError 

pub enum DecodeError {
    TrailingBytes,
    BadKey,
    DuplicateKey,
    InvalidText,
    NestingTooDeep,
    IntegerOutOfRange,
    TooManyElements,
    Malformed,
}

Why decode refused an input: one variant for each reason macula’s reference decoder (macula_record_cbor:decode_strict/1) gives, so an input is refused for the same reason in every stack.

Variants

TrailingBytes

Bytes after the top-level value.

BadKey

A map key that is neither text nor an integer.

DuplicateKey

A map key equal to an earlier key of its map: text with the same bytes, or an integer of the same value, in any width.

InvalidText

Text that is not valid UTF-8.

NestingTooDeep

Arrays and maps nested more than MAX_NESTING_DEPTH levels.

IntegerOutOfRange

An integer below -2^63 or above 2^63-1.

TooManyElements

Input that holds more than MAX_ELEMENTS items.

Malformed

Input that is not one complete item of what the rule allows: truncated input, an indefinite length, a tag, a simple value other than null, or a float that is NaN or infinite.

Trait Implementations

impl Clone for DecodeError

fn clone(&self) -> Self

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

Formats the value using the given formatter.

impl Display for DecodeError

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: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
