Function pin_thread_to_core

pub fn pin_thread_to_core(core: u32) -> Result<(), Error>

Pins the current thread to a specific CPU core.

This function used the sched_setaffinity system call to restrict the current thread to execute only on the specified CPU core.

Note: This does not prevent other threads or processes from being scheduled on the same core. It only restricts where the current thread may run. To achieve true core exclusivity, other threads must be restricted separately.

Arguments

• core - The CPU core number (0-indexed) to pin the thread to.

Returns

• Ok(()) - Thread successfully pinned to core.
• Err(Error) - System called failed (invalid core, permissions, etc.)

Platform Support

This function is Linux-specific and uses the nix crate’s scheduler bindings. On systems without CPU affinity support, this function will return an error.
