Expand description

The underlying nature of the error.

Variants§

§

VisitorDecodeError(DecodeError)

Something went wrong decoding the bytes based on the type and type registry provided.

§

NumberOutOfRange

We cannot decode the number seen into the target type; it’s out of range.

Fields

§value: String

A string representation of the numeric value that was out of range.

§

CannotFindVariant

We cannot find the variant we’re trying to decode from in the target type.

Fields

§got: String

The variant that we are given back from the encoded bytes.

§expected: Vec<&'static str>

The possible variants that we can decode into.

§

WrongLength

The types line up, but the expected length of the target type is different from the length of the input value.

Fields

§actual_len: usize

Length of the type we are trying to decode from

§expected_len: usize

Length fo the type we’re trying to decode into

§

CannotFindField

Cannot find a field that we need to decode to our target type

Fields

§name: String

Name of the field which was not provided.

§

Custom(Box<dyn CustomError>)

A custom error.
