Struct AtomicF64 

pub struct AtomicF64(/* private fields */);

An f64 stored as its bit pattern in an AtomicU64, supporting lock-free updates via a CAS loop. Salmon updates per-transcript mass and the fragment length distribution concurrently from worker threads; this is the building block for that.

Implementations

impl AtomicF64

pub fn new(v: f64) -> Self

pub fn load(&self) -> f64

pub fn store(&self, v: f64)

pub fn fetch_update<F: Fn(f64) -> f64>(&self, f: F) -> f64

Atomically replace the stored value with f(current), returning the new value.

pub fn log_add_assign(&self, log_inc: f64)

Atomically accumulate log_inc into the stored log-space value: self = log(exp(self) + exp(log_inc)). Mirrors salmon’s incLoopLog.

pub fn add_assign(&self, inc: f64)

Atomically add inc in linear space. Mirrors salmon’s incLoop.

impl Default for AtomicF64

fn default() -> Self

Returns the “default value” for a type.
