Crate subetha_pointers 

CXC exotic pointer types.

Each pointer type declares a K_* direction signature via subetha_core::AxisMask, so CXC’s MMF dispatcher can route workloads to the right pointer kind by signature containment.

• umbra_pointer::UmbraPointer<T> for content-prefix
• bloom_pointer::BloomPointer<T> for probabilistic set summary
• kstep_pointer::KStepPointer<T> for log2-strided iteration
• k_tower_pointer::KTower2<T> / k_tower_pointer::KTower3<T> for multi-segment address space
• self_desc_pointer::SelfDescPointer<T> for type discriminant
• versioned_pointer::VersionedPointer<T> / versioned_pointer::HlcVersionedPointer<T> for version metadata
• cardinality_pointer::CardinalityPointer<T> for log2 cardinality
• adaptive_cheri_pointer::ReadableCapability<T> / adaptive_cheri_pointer::WritableCapability<T> for bounds-checked pointers on capability-aware silicon (CHERI / ARM Morello)
• adaptive_rasp_batch::RaspBatch<T> for SIMD-batched bounds + permission checks on x86 (the x86 sibling to CHERI; SoA layout + AVX2 / AVX-512F dispatch)

Stable-Rust portable

No nightly features. The pointer types are pure-Rust structs over *const T / *mut T with content metadata.

Modules

adaptive_cheri_pointer

AdaptiveCheriPointer<T> - CHERI-style capability pointer with software emulation for portability.

adaptive_rasp_batch

RaspBatch<T> - structure-of-arrays (SoA) storage for bounds- checked pointers, designed for high-throughput SIMD batch validation.

bloom_pointer

BloomPointer<T> - pointer carrying a Bloom-filter summary of its target’s contents.

cardinality_pointer

CardinalityPointer<T> - pointer with the cardinality of its target’s reachable set encoded in stolen high bits.

k_tower_pointer

KTowerPointer<T> - recursive pow2-of-pow2 address decomposition.

kstep_pointer

KStepPointer<T> - pointer with first-class stride encoding.

self_desc_pointer

SelfDescPointer<T> - pointer carrying type ID + layout shape in stolen high bits.

umbra_pointer

UmbraPointer<T> - generic content-prefixed pointer.

versioned_pointer

Versioned/MVCC pointers - time-travel addressing for snapshot isolation, immutable trees, and distributed clocks.
