Enum WriteDurability 

pub enum WriteDurability {
    Immediate,
    Eventual,
    None,
}

Durability applied to every catalog-mutation commit. Maps onto redb’s durability levels.

Variants

Immediate

fsync on every commit — crash-safe. The default.

Eventual

Queued for persistence; persists shortly after commit returns. Higher write throughput, may lose the last few commits on a hard crash (the database stays internally consistent).

None

No fsync — fastest writes, durability is best-effort. Intended for bulk import / benchmarking. Note: redb only frees pages at higher durability levels, so exclusive None use grows the file.

Trait Implementations

impl Clone for WriteDurability

fn clone(&self) -> WriteDurability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for WriteDurability

impl Debug for WriteDurability

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

Formats the value using the given formatter.

impl Default for WriteDurability

fn default() -> WriteDurability

Returns the “default value” for a type.

impl Eq for WriteDurability

impl PartialEq for WriteDurability

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