Enum SynchronousMode 

#[repr(u8)]
pub enum SynchronousMode {
    Off = 0,
    Normal = 1,
    Full = 2,
    Extra = 3,
}

Synchronous mode for database writes.

Variants

Off = 0

No syncs at all. Maximum speed, minimum safety.

Normal = 1

Sync at critical moments. Good balance.

Full = 2

Sync after each write. Maximum safety.

Extra = 3

Like Full, but also sync the directory after creating files.

Trait Implementations

impl Clone for SynchronousMode

fn clone(&self) -> SynchronousMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SynchronousMode

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

Formats the value using the given formatter.

impl Default for SynchronousMode

fn default() -> SynchronousMode

Returns the “default value” for a type.

impl Hash for SynchronousMode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SynchronousMode

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