Struct hash_roll::fastcdc::FastCdc

pub struct FastCdc<'a> { /* fields omitted */ }

An instance of the "FastCDC" algorithm

Default parameters:

• Minimum chunk size: 2 KiB
• Maximum chunk size: 64 KiB
• Normal size: 8 KiB
• internal 64-bit gear table: super::gear_table::GEAR_64

Implementations

impl<'a> FastCdc<'a>

pub fn new(
    gear: &'a [u64; 256],
    min_size: u64,
    normal_size: u64,
    max_size: u64
) -> Self

Create a custom FastCDC instance

Trait Implementations

impl<'a> Chunk for FastCdc<'a>

type SearchState = FastCdcState

SearchState allows searching for the chunk edge to resume without duplicating work already done.

fn to_search_state(&self) -> Self::SearchState

Provide an initial [SearchState] for use with [find_chunk_edge()]. Generally, for each input one should generate a new [SearchState].

fn find_chunk_edge(
    &self,
    state: &mut Self::SearchState,
    data: &[u8]
) -> (Option<usize>, usize)

Find the next "chunk" in data to emit

impl<'a> Clone for FastCdc<'a>

fn clone(&self) -> FastCdc<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for FastCdc<'a>

impl<'a> Debug for FastCdc<'a>

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

Formats the value using the given formatter.

impl<'a> Default for FastCdc<'a>

fn default() -> Self

Returns the "default value" for a type.

impl<'a> Eq for FastCdc<'a>

impl<'a, '_> From<&'_ FastCdc<'a>> for FastCdcIncr<'a>

fn from(params: &FastCdc<'a>) -> Self

Performs the conversion.

impl<'a> PartialEq<FastCdc<'a>> for FastCdc<'a>

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

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

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl<'a> ToChunkIncr for FastCdc<'a>

type Incr = FastCdcIncr<'a>

Incr provides the incrimental interface to this chunking instance

fn to_chunk_incr(&self) -> Self::Incr

to_chunk_incr() returns a ChunkIncr which can be incrimentally fed data and emits chunks.
