Struct Tsc 

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

The x86_64 timestamp counter (TSC).

Note that not all TSC implementations have a constant frequency. On Linux, try_new_linux_sys checks that the frequency is constant.

Implementations

impl Tsc

pub fn try_new_assume_stable() -> Result<Self, TscUnavailable>

Returns Ok(Tsc) if the CPUID TSC flag is set.

The TSC flag indicates the counter exists but does not guarantee stability across cores or CPU power states. Prefer Tsc::try_new_linux_sys on Linux.

pub fn try_new_linux_sys() -> Result<Self, TscUnavailable>

Returns Ok(Tsc) if the Linux kernel reports tsc as an available clocksource.

A TSC listed as an available clocksource means the kernel has verified stability across cores and power state changes, making it safe for benchmarking.
