Expand description

An error decoding SCALE bytes.

Variants

`BitSequenceError(BitSequenceError)`

We ran into an error trying to decode a bit sequence.

`CannotDecodeCompactIntoType(Type<PortableForm>)`

The type we’re trying to decode is supposed to be compact encoded, but that is not possible.

`InvalidStr(Utf8Error)`

Failure to decode bytes into a string.

`InvalidChar(u32)`

We could not convert the u32 that we found into a valid char.

`Eof`

We expected more bytes to finish decoding, but could not find them.

`VariantNotFound(u8, TypeDefVariant<PortableForm>)`

We found a variant that does not match with any in the type we’re trying to decode from.

`CodecError(Error)`

Some error emitted from a codec::Decode impl.

`TypeIdNotFound(u32)`

We could not find the type given in the type registry provided.

`NothingLeftToDecode`

You hit this is you try to decode a field from an
