Enum BackendError

#[non_exhaustive]
pub enum BackendError {
Show 14 variants BadHMAC, Argon2Failure { source: Error, }, KeyDeserialization, ItemSerialization, ItemDeserialization, Compression { source: Error, }, Decompression { source: Error, }, SegmentIO { source: Error, }, SegmentLength, NoData, NoDataIO { source: Error, }, InvalidCompression, EntryIO { source: Error, }, InvalidLsmState,
}
Expand description

Error type describing faults that can happen during encryption or decryption.

This is a fairly low level type for interacting with the api directly, you probably want CryptoBoxError

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
