Struct pancake_engine_common::memlog_w::WritableMemLog

pub struct WritableMemLog<K, V> {
    r_memlog: ReadonlyMemLog<K, V>,
    log_writer: BufWriter<File>,
}

A MemLog is a sorted dictionary (called Memtable), backed up by a write-ahead log file.

Fields

r_memlog: ReadonlyMemLog<K, V>

log_writer: BufWriter<File>

Implementations

impl<K, V> WritableMemLog<K, V>

pub fn r_memlog(&self) -> &ReadonlyMemLog<K, V>

pub fn set_r_memlog(&mut self, value: ReadonlyMemLog<K, V>) -> &mut Self

pub fn set_log_writer(&mut self, value: BufWriter<File>) -> &mut Self

impl<K, V> WritableMemLog<K, V>

where K: Serializable + Ord, V: Serializable,

pub fn load_or_new<P: AsRef<Path>>(log_path: P) -> Result<Self>

pub fn put(&mut self, k: K, v: V) -> Result<()>

The caller is responsible for Self::flush()ing subsequently.

pub fn flush(&mut self) -> Result<()>

pub fn clear(&mut self) -> Result<()>

Trait Implementations

impl<K, V> From<WritableMemLog<K, V>> for ReadonlyMemLog<K, V>

fn from(w_memlog: WritableMemLog<K, V>) -> ReadonlyMemLog<K, V>

Converts to this type from the input type.
