Builder for QueryDbConfig.
Implementations§
Source§impl QueryDbConfigBuilder
impl QueryDbConfigBuilder
Sourcepub fn shard_count(self, count: usize) -> Self
pub fn shard_count(self, count: usize) -> Self
Sets the number of cache shards. Must be a power of two.
§Panics
Panics if count is not a power of two or is zero.
Sourcepub fn compaction_fragmentation_threshold(self, threshold: f64) -> Self
pub fn compaction_fragmentation_threshold(self, threshold: f64) -> Self
Sets the arena fragmentation threshold (0.0–1.0).
Sourcepub fn compaction_delta_ratio_threshold(self, threshold: f64) -> Self
pub fn compaction_delta_ratio_threshold(self, threshold: f64) -> Self
Sets the delta buffer ratio threshold (0.0–1.0).
Sourcepub fn derived_persistence_filename(self, filename: impl Into<String>) -> Self
pub fn derived_persistence_filename(self, filename: impl Into<String>) -> Self
Sets the derived persistence filename.
Sourcepub fn enable_background_compaction(self, enable: bool) -> Self
pub fn enable_background_compaction(self, enable: bool) -> Self
Enables or disables background compaction.
Sourcepub fn max_entry_size_bytes(self, bytes: usize) -> Self
pub fn max_entry_size_bytes(self, bytes: usize) -> Self
Sets the maximum serialized size (in bytes) for a single cached entry.
Entries that exceed this limit are evaluated normally but not stored in
the cache. See QueryDbConfig::max_entry_size_bytes for full
semantics.
§Panics
Panics if bytes is zero.
Sourcepub fn build(self) -> QueryDbConfig
pub fn build(self) -> QueryDbConfig
Builds the config.
