Struct ScopedFtz 

pub struct ScopedFtz { /* private fields */ }

RAII guard that enables FTZ/DAZ on construction and restores the previous FPU control register state on drop, scoping the effect to a block.

Usage

{
    let _guard = ScopedFtz::new();
    // FTZ/DAZ active here
} // previous FPU state restored on drop

On unsupported platforms this is a no-op. The guard is !Send because FPU control registers are per-thread state.

Implementations

impl ScopedFtz

pub fn new() -> Self

Enable FTZ/DAZ and save the current register state for restoration on drop.

Trait Implementations

impl Default for ScopedFtz

fn default() -> Self

Returns the “default value” for a type.

impl Drop for ScopedFtz

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
