pub struct PrivateRecordContext { /* private fields */ }Expand description
Values bound to one private record and its Golden decryption shares.
The format version is part of the context, so both encryption layers authenticate it. A record that holds one format cannot be read as another format.
Implementations§
Source§impl PrivateRecordContext
impl PrivateRecordContext
Sourcepub const fn new(
chain_id: PrivateRecordChainId,
key_epoch: StorageKeyEpoch,
transaction_id: TransactionId,
) -> Self
pub const fn new( chain_id: PrivateRecordChainId, key_epoch: StorageKeyEpoch, transaction_id: TransactionId, ) -> Self
Creates a context for a new record in the current format.
Sourcepub const fn with_format_version(
chain_id: PrivateRecordChainId,
key_epoch: StorageKeyEpoch,
transaction_id: TransactionId,
format_version: PrivateRecordFormatVersion,
) -> Self
pub const fn with_format_version( chain_id: PrivateRecordChainId, key_epoch: StorageKeyEpoch, transaction_id: TransactionId, format_version: PrivateRecordFormatVersion, ) -> Self
Creates a context for a stored record in the given format.
The caller must supply the version that the record was sealed with. A different version produces a context that fails to authenticate the record.
Sourcepub const fn chain_id(&self) -> PrivateRecordChainId
pub const fn chain_id(&self) -> PrivateRecordChainId
Returns the chain identifier.
Sourcepub const fn key_epoch(&self) -> StorageKeyEpoch
pub const fn key_epoch(&self) -> StorageKeyEpoch
Returns the storage key epoch.
Sourcepub const fn transaction_id(&self) -> TransactionId
pub const fn transaction_id(&self) -> TransactionId
Returns the transaction identifier.
Sourcepub const fn format_version(&self) -> PrivateRecordFormatVersion
pub const fn format_version(&self) -> PrivateRecordFormatVersion
Returns the record format version.
Sourcepub fn to_bytes(self) -> Vec<u8> ⓘ
pub fn to_bytes(self) -> Vec<u8> ⓘ
Returns the canonical context used by the record cipher and Golden.
Sourcepub fn try_from_bytes(bytes: &[u8]) -> Result<Self, PrivateRecordError>
pub fn try_from_bytes(bytes: &[u8]) -> Result<Self, PrivateRecordError>
Parses a canonical schema version 1 context produced by Self::to_bytes.
Rejects any input whose domain tag, length, or format version differ from schema version 1, or whose transaction id is not canonical.
