Enum ArchiveError

pub enum ArchiveError {
    UnsupportedVersion(u16),
    MissingMetadata,
    InvalidFrame(&'static str),
    AesGcm(Error),
    IO(Error),
    Decode(DecodeError),
    Storage(StorageError),
    InvalidKeyLength(usize),
    UnreadableGroup {

        source: UnreadableGroup,
    },
}

Expand description

Archive export or import failure.

Variants§

UnsupportedVersion(u16)

Unsupported archive version.

The archive was written by a newer client. Not retryable.

MissingMetadata

Missing metadata.

The archive has no metadata frame. Not retryable.

InvalidFrame(&'static str)

Invalid archive frame.

The archive framing is incomplete or malformed. Not retryable.

AesGcm(Error)

AES-GCM error.

Encryption or decryption failed; on import, usually a wrong key. Not retryable.

IO(Error)

I/O error.

Reading or writing the archive failed. May be retryable.

Decode(DecodeError)

Decode error.

An archive element is not valid protobuf. Not retryable.

Storage(StorageError)

InvalidKeyLength(usize)

Invalid key length.

The archive key is not ENC_KEY_SIZE bytes. Rejected before any archive byte is read or written. Not retryable.

UnreadableGroup

Unreadable group.

A selected group’s MLS state or metadata cannot be read, so export fails rather than omit it. Retryable only when reading its MLS state failed transiently.

Fields

§group_id: GroupId

§source: UnreadableGroup
