Crate stable_intrinsics 

Stable intrinsics

This crate wraps irreplacable instrisic functions on nightly, and re-implements it otherwise.

Traits

DisjointBitOr

Same as core::intrinsics::fallback::DisjointBitOr except it is not const due to stable and beta limitations.

Functions

abort

Same as std::intrinsics::abort on nightly. On stable and beta, the exact behavior depends on whether or not that std is avalible.

breakpoint

Same as std::intrinsics::breakpoint on nightly. On stable and beta, the implementation depends on the target architecture.

cold_path

Same as core::intrinsics::cold_path on nightly. On stable and beta, it is a no-op.

disjoint_bitor^⚠

Same as core::intrinsics::disjoint_bitor on nightly except the const-ness. On stable and beta, it is implemented with core::hint::assert_unchecked.

likely

Same as core::intrinsics::likely on nightly. On stable and beta, it is an identity function.

nontemporal_store^⚠

Same as core::intrinsics::nontemporal_store on nightly. On stable and beta, it is simply a pointer store.

prefetch_read_data^⚠

Same as core::intrinsics::prefetch_read_data on nightly. On stable and beta, it is a no-op.

prefetch_read_instruction^⚠

Same as core::intrinsics::prefetch_read_instruction on nightly. On stable and beta, it is a no-op.

prefetch_write_data^⚠

Same as core::intrinsics::prefetch_write_data on nightly. On stable and beta, it is a no-op.

prefetch_write_instruction^⚠

Same as core::intrinsics::prefetch_write_instruction on nightly. On stable and beta, it is a no-op.

raw_eq^⚠

Same as core::intrinsics::raw_eq on nightly. On stable and beta, a and b are converted into [u8] before comparason.

select_unpredictable

Same as core::intrinsics::select_unpredictable on nightly. On stable and beta, use an if-else to determine the output.

transmute_unchecked^⚠

Same as core::intrinsics::transmute_unchecked.

unlikely

Same as core::intrinsics::unlikely on nightly. On stable and beta, it is an identity function.
