}
Expand description

Errors that can occur while decoding.

Variants

InvalidByte(usizeu8)

An invalid byte was found in the input. The offset and offending byte are provided.

InvalidLength

The length of the input is invalid. A typical cause of this is stray trailing whitespace or other separator bytes. In the case where excess trailing bytes have produced an invalid length and the last byte is also an invalid base64 symbol (as would be the case for whitespace, etc), InvalidByte will be emitted instead of InvalidLength to make the issue easier to debug.

InvalidLastSymbol(usizeu8)

The last non-padding input symbol’s encoded 6 bits have nonzero bits that will be discarded. This is indicative of corrupted or truncated Base64. Unlike InvalidByte, which reports symbols that aren’t in the alphabet, this error is for symbols that are in the alphabet but represent nonsensical encodings.

Use this to cast from one trait object type to another. This method is more customizable than the dyn_cast method. Here you can also specify the “source” trait from which the cast is defined. This can for example allow using casts from a supertrait of the current trait object. Read more
