Struct PropagateOptions 

pub struct PropagateOptions {
    pub target_bucket_len: usize,
    pub min_buckets: usize,
}

Tuning knobs for propagate_with; Default is what propagate uses.

Fields

target_bucket_len: usize

Terms per bucket the per-layer partition targets.

Above the min_buckets floor raising this alone does nothing; both fields must move together to get fewer buckets, and rebucketing is grow-only, so lowering either mid-run never coarsens a partition. At least 1 (validate).

min_buckets: usize

Floor on the per-layer bucket count once the sum is worth splitting.

At least 16, so a sum of at most 1024 terms keeps one bucket (validate).

Implementations

impl PropagateOptions

pub fn validate(&self) -> Result<(), String>

Err with the message every entry point panics with unless target_bucket_len >= 1 and min_buckets >= 16.

Trait Implementations

impl Clone for PropagateOptions

fn clone(&self) -> PropagateOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PropagateOptions

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

Formats the value using the given formatter.

impl Default for PropagateOptions

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for PropagateOptions

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