Variants

Io(Error)

An I/O error happened

Check the inner error for more information

BlockNotFound

We couldn’t find the block we were looking for

IndexIsFull

The index is full, we can’t add more blocks to it

Tried to open a database with an unsupported version number

Poisoned

Our cache lock is poisoned

InvalidMagic(u32)

We encountered an invalid magic value, possibly database corruption

AccumulatorTooBig

The provided accumulator is too big

IndexTooBig

Tried to create an index more than 31 bits long

InvalidMetadataPointer

Something wrong happened with the metadata file mmap

DbCorrupted

The database is corrupted

InvalidValidationIndex

The validation index doesn’t have a height. This probably means it is in a fork or invalid chain
