Implementations

impl OptimizationHints

pub fn likely(b: bool) -> bool

Hint to the compiler that a branch is likely to be taken

pub fn unlikely(b: bool) -> bool

Hint to the compiler that a branch is unlikely to be taken

pub fn assume_aligned<T>(ptr: *const T, align: usize) -> *const T

Hint that a pointer is aligned to SIMD boundaries

pub fn assume_aligned_mut<T>(ptr: *mut T, align: usize) -> *mut T

Hint that a pointer is aligned to SIMD boundaries (mutable)

pub fn assume_range<T: PartialOrd + Copy>(value: T, min: T, max: T) -> T

Hint that a value is within a specific range

pub fn assume_len<T>(slice: &[T], len: usize) -> &[T]

Hint that a slice has a specific length

pub fn assume_len_mut<T>(slice: &mut [T], len: usize) -> &mut [T]

Hint that a slice has a specific length (mutable)

pub fn assume_loop_count(count: usize) -> usize

Hint that a loop will iterate a specific number of times

pub fn prefetch_read<T>(_ptr: *const T)

Hint that data is hot (frequently accessed)

pub fn prefetch_write<T>(_ptr: *const T)

Hint that data will be written to (for write prefetching)
