Struct AutoBackendProfile 

pub struct AutoBackendProfile {
    pub brute_force_pair_limit: usize,
    pub kd_target_minimum: usize,
    pub kd_query_ratio: usize,
}

Tunable decisions used when SpatialBackend::Auto is requested.

Fields

brute_force_pair_limit: usize

Largest Cartesian product evaluated directly.

kd_target_minimum: usize

Smallest target set for which a k-d tree may be selected.

kd_query_ratio: usize

Required target-to-query size ratio for selecting a k-d tree.

Implementations

impl AutoBackendProfile

pub const BALANCED: Self

General-purpose profile used by Default.

pub fn validate(self) -> Result<(), SpatialError>

Validates that every threshold defines an unambiguous plan.

Errors

Returns the first invalid automatic-planning field.

pub fn resolve( self, left_count: usize, right_count: usize, ) -> Result<SpatialBackend, SpatialError>

Resolves one workload after validating the profile.

The same cost ladder holds for periodic workloads: a k-d tree keeps wrapped targets and queries lattice images, a cell list builds the fractional-coordinate grid, and brute force stays the small-workload choice. Selection is never pinned by periodicity alone.

Errors

Returns an error when the profile is invalid.
