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 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 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.

Trait Implementations

impl Clone for DataMap

fn clone(&self) -> DataMap

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DataMap

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DataMap

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Ord for DataMap

fn cmp(&self, other: &DataMap) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for DataMap

fn eq(&self, other: &DataMap) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for DataMap

fn partial_cmp(&self, other: &DataMap) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for DataMap

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
