Enum lmdb_zero::error::Error

pub enum Error {
    Code(c_int),
    NulStr,
    Reopened,
    Mismatch,
    ValRejected(String),
    // some variants omitted
}

Error type returned by LMDB.

Variants

Code(c_int)

A basic error code returned by LMDB.

The code is generally expected to be a constant defined in the errors module if negative, or a raw platform error code if positive.

NulStr

A string path was given which contains a NUL byte.

Reopened

An attempt was made to open a database which is already open.

Mismatch

An attempt was made to use two items together which cannot be used together.

For example, trying to use a cursor from one transaction to access data in another.

ValRejected(String)

A value conversion was rejected. A message explaining why is included.
