Structs

ByteLruCache

Byte-limited LRU cache with an optional entry cap.

Governed

A value whose live memory is coupled to a process-wide reservation.

MaterializationPolicy

MemoryGovernor

Process-wide byte-accounting governor for large allocations.

MemoryReservation

RAII guard for bytes reserved on a MemoryGovernor ledger; dropping it releases the reservation. Hold it exactly as long as the accounted allocation is live.

ProblemHints

Hints that flip strict mode on regardless of n/p — used when a code path is structurally operator-only and any dense fallback would be a bug.

RayonSafeOnce

Lazy-init cache safe to call from inside rayon par_iter.

ResourcePolicy

Enums

DerivativeStorageMode

MatrixMaterializationError

MemoryReservationError

Typed refusal from MemoryGovernor::try_reserve.

Constants

LIBRARY_ROW_CHUNK_TARGET_BYTES

The library-default streamed row-chunk target (8 MiB), shared as a const so compile-time consumers (e.g. device tile geometry) stay in lockstep with ResourcePolicy::default_library without a runtime policy query.

OWNED_DATA_CACHE_MAX_ENTRIES

Traits

ResidentBytes

Functions

dense_f64_bytes

Checked byte footprint of a dense nrows × ncols f64 matrix.

prediction_chunk_rows

Select the row count for prediction-time covariance work.

rows_for_target_bytes

Returns how many rows to stream per chunk so that each chunk uses approximately target_bytes given a row width of cols f64 entries.
