Struct asuran_core::repository::chunk::ChunkID

pub struct ChunkID { /* fields omitted */ }

Key used for indexing a Chunk in a repository

These are usually derived via an HMAC of the chunks plain text, and are used for reduplication. If two chunks have the same ChunkID, it is assumed that they are identical.

Implementations

impl ChunkID

pub fn new(input_id: &[u8]) -> ChunkID

Will create a new key from a slice.

Keys longer than 32 bytes will be truncated. Keys shorter than 32 bytes will be padded at the end with zeros.

pub fn get_id(&self) -> &[u8]

Provides a reference to a key's raw bytes

pub fn verify(&self, slice: &[u8]) -> bool

Verifies equaliy of this key with the first 32 bytes of a slice

pub fn manifest_id() -> ChunkID

Returns the special all-zero key used for the manifest

pub fn random_id() -> ChunkID

Returns a random id, used for testing
