Expand description

Errors that can occur while unsigning a “signed value”.

Variants

`SeparatorNotFound`

Fields

separator: Separator

A string was provided to unsign, but it did not contain the expected separator.

`SignatureMismatch`

Fields

signature: &'a str

value: &'a str

The signature did not match what we expected it to be.

`PayloadInvalid`

Fields

value: &'a str

error: PayloadError

The payload is invalid, e.g. it cannot be parsed.
