Implementations§

Source§

impl Database

Source

pub fn open(path: &Path) -> Result<Self, DiskMapError>

Source

pub fn document<K, V>(&self, name: &str) -> Result<DiskMap<K, V>, DiskMapError>

Source

pub fn drop(&self, name: &str) -> bool

Source

pub fn list(&self) -> Vec<String>

Source

pub fn size_on_disk(&self) -> Result<u64, DiskMapError>

Returns the on-disk size of the storage files for this database.

Source

pub async fn flush(&self) -> Result<usize, DiskMapError>

Asynchronously flushes all dirty IO buffers and calls fsync.

If this succeeds, it is guaranteed that all previous writes will be recovered if the system crashes.

Returns the number of bytes flushed during this call.

Flushing can take quite a lot of time, and you should measure the performance impact of using it on realistic sustained workloads running on realistic hardware.
