Struct ethcore::snapshot::io::LooseWriter

source · [−]

pub struct LooseWriter { /* private fields */ }

Expand description

A “loose” writer writes chunk files into a directory.

Implementations

source

impl LooseWriter

source

pub fn new(path: PathBuf) -> Result<Self>

Create a new LooseWriter which will write into the given directory, creating it if it doesn’t exist.

Trait Implementations

source

impl SnapshotWriter for LooseWriter

source

fn write_state_chunk(&mut self, hash: H256, chunk: &[u8 ]) -> Result<()>

Write a compressed state chunk.

source

fn write_block_chunk(&mut self, hash: H256, chunk: &[u8 ]) -> Result<()>

Write a compressed block chunk.

source

fn finish(self, manifest: ManifestData) -> Result<()>

Complete writing. The manifest’s chunk lists must be consistent with the chunks written. Read more
