Struct DataMap 

pub struct DataMap(/* private fields */);

Holds the information that is required to recover the content of the encrypted file. This is held as a vector of ChunkInfo, i.e. a list of the file’s chunk hashes. Only files larger than 3072 bytes (3 * MIN_CHUNK_SIZE) can be self-encrypted. Smaller files will have to be batched together.

Implementations

impl DataMap

pub fn instance_of<V: NapiRaw>(env: Env, value: V) -> Result<bool>

impl DataMap

pub fn into_reference(val: DataMap, env: Env) -> Result<Reference<DataMap>>

pub fn into_instance(self, env: Env) -> Result<ClassInstance<DataMap>>

impl DataMap

pub fn new(keys: Vec<&ChunkInfo>) -> Self

A new instance from a vec of partial keys.

Sorts on instantiation. The algorithm requires this to be a sorted list to allow get_pad_iv_key to obtain the correct pre-encryption hashes for decryption/encryption.

pub fn with_child(keys: Vec<&ChunkInfo>, child: BigInt) -> Result<Self>

Creates a new DataMap with a specified child value

pub fn original_file_size(&self) -> usize

Original (pre-encryption) size of the file.

pub fn infos(&self) -> Vec<ChunkInfo>

Returns the list of chunks pre and post encryption hashes if present.

pub fn child(&self) -> Option<usize>

Returns the child value if set

pub fn len(&self) -> usize

Returns the number of chunks in the DataMap

pub fn is_child(&self) -> bool

Returns true if this DataMap has a child value
