Enum CodecError 

pub enum CodecError {
    WrongType,
    IntegerOverflow,
    NotFinite,
    FloatRange,
    NotUtf8,
    WrongArity,
    UnknownTermType,
}

Error returned by term type conversion operations.

otter’s internal error type — it never appears in user NIF signatures. The #[otter::nif] macro converts codec failures to badarg automatically.

Variants

WrongType

The term was not the expected type.

IntegerOverflow

An integer term did not fit the requested Rust integer type.

NotFinite

A float value could not be represented as an Erlang float because it is not finite (NaN or infinity) — an encode-side failure.

FloatRange

A finite float term fell outside the finite range of the requested Rust float type (only f32, on decode).

NotUtf8

A binary’s bytes were not valid UTF-8, or a list was not a valid string, when decoding to a Rust String.

WrongArity

An Erlang tuple’s arity did not match the arity of the Rust tuple type it was being decoded into.

UnknownTermType

The term’s type code is one this otter build does not recognize — a term type added by a newer OTP than otter knows about.

Trait Implementations

impl Clone for CodecError

fn clone(&self) -> CodecError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CodecError

impl Debug for CodecError

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

Formats the value using the given formatter.

impl Display for CodecError

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

Formats the value using the given formatter.

impl Eq for CodecError

impl Error for CodecError

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 CodecError

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