Struct GeometricMemoizationConfig 

#[non_exhaustive]
pub struct GeometricMemoizationConfig { /* private fields */ }

Tuning controls for LcpMemoizationPolicy::Geometric.

The defaults were selected on a complete ruSTAR-shaped GRCh38 plus GENCODE workload. Tables are local to a single phase-4 partition cascade and are dropped when that partition is emitted.

use caps_sa::{GeometricMemoizationConfig, LcpMemoizationPolicy};
use std::num::NonZeroUsize;

let config = GeometricMemoizationConfig::default()
    .with_probe_symbols(NonZeroUsize::new(512).unwrap());
let policy = LcpMemoizationPolicy::from(config);

Implementations

impl GeometricMemoizationConfig

pub const DEFAULT: Self

The default configuration measured on ruSTAR-shaped GRCh38 plus GENCODE input.

pub const fn probe_symbols(&self) -> usize

Number of symbols compared normally before an active-table lookup.

pub const fn with_probe_symbols(self, probe_symbols: NonZeroUsize) -> Self

Return this configuration with a new ordinary-comparison probe length.

Production callers should normally retain the measured default so short comparisons stay on the direct path.

pub const fn min_lcp_symbols(&self) -> usize

Minimum exact LCP length, including any prefix already known by the merge, that is eligible for admission.

pub const fn with_min_lcp_symbols(self, min_lcp_symbols: NonZeroUsize) -> Self

Return this configuration with a new exact-LCP admission threshold.

pub const fn activate_after_entries(&self) -> usize

Number of learned entries required before a partition starts looking entries up.

pub const fn with_activate_after_entries( self, activate_after_entries: NonZeroUsize, ) -> Self

Return this configuration with a new lazy-activation threshold.

If this exceeds Self::max_entries_per_partition, that partition remains in the training kernel for its entire lifetime.

pub const fn max_entries_per_partition(&self) -> usize

Hard entry bound for one phase-4 partition table.

pub const fn with_max_entries_per_partition( self, max_entries_per_partition: NonZeroUsize, ) -> Self

Return this configuration with a new per-partition entry bound.
