Struct CpuFeatures 

Source 
pub struct CpuFeatures { /* private fields */ }
Expand description

CPU hardware features that affect performance

Provides platform-specific CPU feature detection with caching. Detection is performed once and cached for the lifetime of the process.

impl PartialEq for CpuFeatures

Source§

fn eq(&self, other: &CpuFeatures) -> bool
