Enum FlushPolicy 

pub enum FlushPolicy {
    Never,
    Manual,
    Always,
    EveryBytes(usize),
    EveryWrites(usize),
    EveryMillis(u64),
}

Policy controlling when to flush dirty pages to disk.

Variants

Never

Never flush implicitly; flush() must be called by the user.

Manual

Alias of Never for semantic clarity when using the builder API.

Always

Flush after every write/update_region call.

EveryBytes(usize)

Flush when at least N bytes have been written since the last flush.

EveryWrites(usize)

Flush after every W writes (calls to update_region).

EveryMillis(u64)

Flush automatically every N milliseconds when there are pending writes.

Trait Implementations

impl Clone for FlushPolicy

fn clone(&self) -> FlushPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FlushPolicy

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

Formats the value using the given formatter.

impl Default for FlushPolicy

fn default() -> FlushPolicy

Returns the “default value” for a type.

impl PartialEq for FlushPolicy

fn eq(&self, other: &FlushPolicy) -> 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.
