Struct self_encryption::ChunkInfo

pub struct ChunkInfo {
    pub index: usize,
    pub dst_hash: XorName,
    pub src_hash: XorName,
    pub src_size: usize,
}

This is - in effect - a partial decryption key for an encrypted chunk of data.

It holds pre- and post-encryption hashes as well as the original (pre-compression) size for a given chunk. This information is required for successful recovery of a chunk, as well as for the encryption/decryption of it’s two immediate successors, modulo the number of chunks in the corresponding DataMap.

Fields

index: usize

Index number (zero-based)

dst_hash: XorName

Post-encryption hash of chunk

src_hash: XorName

Pre-encryption hash of chunk

src_size: usize

Size before encryption and compression (any possible padding depending on cipher used alters this)

Trait Implementations

impl Clone for ChunkInfo

fn clone(&self) -> ChunkInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ChunkInfo

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

Formats the value using the given formatter.

impl Default for ChunkInfo

fn default() -> ChunkInfo

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ChunkInfo

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Ord for ChunkInfo

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<ChunkInfo> for ChunkInfo

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<ChunkInfo> for ChunkInfo

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for ChunkInfo

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

Serialize this value into the given Serde serializer.

impl Eq for ChunkInfo

impl StructuralEq for ChunkInfo
