Level

Struct Level 

Source
pub struct Level(/* private fields */);
Expand description

An opaque representation of an Architecture’s capability level.

Level allows comparing the relative capabilities of different architectures without requiring an instance of the architecture type. This is useful for compile-time checks against crate::ARCH where constructing architecture types like x86_64::V3 would require unsafe.

Levels are totally ordered within an ISA family, with greater values indicating more capable instruction sets. Scalar is always the lowest level.

§Examples

Checking if the compile-time architecture meets a minimum capability:

#[cfg(target_arch = "x86_64")]
use diskann_wide::{Architecture, arch};

// Check at compile time whether we were built with AVX2+ support.
#[cfg(target_arch = "x86_64")]
let _meets_v3 = arch::Current::level() >= arch::x86_64::V3::level();
