Expand description

Represents the failures that can occur in an Ockam FFI Vault.

Variants

`VaultDoesNotSupportPersistence`

Persistence is not supported for this Vault implementation.

`ErrorCreatingFilesystemVault`

An underlying filesystem error prevented Vault creation.

`InvalidParam`

Invalid parameter.

`EntryNotFound`

Entry not found.

`UnknownPublicKeyType`

Unknown public key type.

`InvalidString`

Invalid string.

`BufferTooSmall`

Buffer is too small.

`InvalidPublicKey`

A public key is invalid.

`VaultNotFound`

No such Vault.

`OwnershipError`

Ownership error.

`UnexpectedPanic`

Caught a panic (which would be UB if we let it unwind across the FFI).
