Enum fjall::PersistMode

pub enum PersistMode {
    Buffer,
    SyncData,
    SyncAll,
}

The persist mode allows setting the durability guarantee of previous writes

Variants

Buffer

Flushes data to OS buffers. This allows the OS to write out data in case of an application crash.

When this function returns, data is not guaranteed to be persisted in case of a power loss event or OS crash.

SyncData

Flushes data using fdatasync.

Use if you know that fdatasync is sufficient for your file system and/or operating system.

SyncAll

Flushes data + metadata using fsync.

Trait Implementations

impl Clone for PersistMode

fn clone(&self) -> PersistMode

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PersistMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for PersistMode

fn eq(&self, other: &PersistMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
