Normal

普通模式（默认）

Full

完全同步（最安全，最慢）

Extra

额外同步

Implementations

impl SynchronousMode

pub fn as_pragma(&self) -> &'static str

转换为 PRAGMA 值

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 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.

impl Copy for SynchronousMode

impl Eq for SynchronousMode

impl StructuralPartialEq for SynchronousMode
