Struct LocalSpillStore 

pub struct LocalSpillStore { /* private fields */ }

A SpillStore that writes temporary files to a local temp directory.

By default there is no disk cap. Use LocalSpillStore::with_cap to configure one shared across every handle this store produces.

The temp directory is deleted when the store is dropped, cleaning up any files whose handles have already been dropped.

Implementations

impl LocalSpillStore

pub fn new() -> Result<Self>

Create a store with no disk cap.

pub fn with_cap(cap_bytes: u64) -> Result<Self>

Create a store that returns lance_core::Error::DiskCapExceeded once total bytes written across all live handles would exceed cap_bytes.
