Struct ChunkIdentifierGenerator

Source

pub struct ChunkIdentifierGenerator { /* private fields */ }

Expand description

Generator for Chunk’s identifier.

Each Chunk has a unique identifier. This generator generates the unique identifiers.

In order to keep good performance, a unique identifier is simply a u64 (see ChunkIdentifier). Generating a new unique identifier boils down to incrementing by one the previous identifier. Note that this is not an index: it is an identifier.

Implementations§

Source §

impl ChunkIdentifierGenerator

Source

pub fn new_from_scratch() -> ChunkIdentifierGenerator

Create the generator assuming the current LinkedChunk it belongs to is empty.

Source

pub fn new_from_previous_chunk_identifier( last_chunk_identifier: ChunkIdentifier, ) -> ChunkIdentifierGenerator

Create the generator assuming the current LinkedChunk it belongs to is not empty, i.e. it already has some Chunk in it.
