    pub cache_capacity: usize,
    pub cache_evict_pct: usize,
    pub pool_capacity: usize,
    pub checkpoint_size: usize,

}

Fields

cache_capacity: usize

Per-bucket target resident bytes for mapped B+Tree pages.

cache_evict_pct: usize

Percentage of items evicted per round. Range is [10, 80], default is 20%

pool_capacity: usize

Per-bucket pool target bytes. Default is Self::POOL_CAP

checkpoint_size: usize

Maximum bytes a single checkpoint round should emit. Default is Self::CHECKPOINT_SIZE

inline_size: usize

For branch nodes, keys and indexes are always inlined. For leaf nodes, values smaller than Self::MIN_INLINE_SIZE are always inlined, and values larger than Self::MAX_INLINE_SIZE are stored as blobs. Default is Self::MIN_INLINE_SIZE

split_elems: u16

Maximum number of elements in an SST (B+Tree node). Default is Self::MAX_SPLIT_ELEMS

consolidate_threshold: u16

Threshold for consolidating delta chains. Range is [16, Self::split_elems / 2]

enable_backpressure: bool

Enable foreground write backpressure. Default is true

_padding: [u8; 3]

Trait Implementations

impl Clone for BucketOptions

fn clone(&self) -> BucketOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BucketOptions

impl Debug for BucketOptions

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

Formats the value using the given formatter.

impl Default for BucketOptions

fn default() -> Self

Returns the “default value” for a type.

impl Eq for BucketOptions

impl PartialEq for BucketOptions

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