Struct Store 

pub struct Store { /* private fields */ }

Rows by key, iterated in key order.

Implementations

impl Store

pub fn in_memory() -> Store

A store that keeps everything in memory.

pub fn spilling(dir: PathBuf, budget: usize) -> Result<Store>

A store that writes blobs into dir once those in memory exceed budget bytes.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn get(&self, key: &str) -> Option<Js>

The row under key, with any spilled blob read back.

pub fn peek(&self, key: &str) -> Option<&Js>

A reference to the row as stored (a spilled blob reads as empty).

pub fn contains(&self, key: &str) -> bool

pub fn put(&mut self, key: &str, value: Js)

pub fn delete(&mut self, key: &str)

pub fn keys(&self, prefix: &str) -> Vec<String>

Keys under prefix, in key order.

pub fn delete_prefix(&mut self, prefix: &str)

pub fn iter(&self) -> impl Iterator<Item = (&String, &Js)>

Every row, in key order (spilled blobs read as empty; see Store::get).

pub fn blob_bytes(&self) -> usize

Blobs held in memory, in bytes.

pub fn spilled(&self) -> usize

Rows whose blob lives in the spill directory.

Trait Implementations

impl Drop for Store

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
