Struct ThreadPool 

pub struct ThreadPool { /* private fields */ }

Implementations

impl ThreadPool

pub fn execute<F>(&self, f: F) -> Result<(), Box<dyn Error>>

where F: FnOnce() + Send + 'static,

Executes a job on the thread pool.

Behavior

• Single-threaded mode (max_jobs=1): Job executes synchronously in the calling thread
• Multi-threaded mode: Job is queued and executed asynchronously by worker threads

pub fn is_single_threaded(&self) -> bool

Returns true if running in single-threaded mode.

Single-threaded mode is active when max_jobs=1, resulting in:

• No worker threads spawned
• No message passing channel created
• All jobs executed synchronously in the main thread
