enum DbErrorKind

Why a database operation failed.

Example:

oxl✓ checked in CI

fn advice(k: DbErrorKind) -> str {
  match k {
    .Conflict => "the key exists"
    .NotFound => "no such row"
    .Busy => "retry"
    .Other => "give up"
    .CrossShardTx => "keep a transaction on one shard"
  }
}

fn main() io {
  print(advice(DbErrorKind.Busy))
}

Output

retry
