Generates the base configuration for spawning a thread, from which configuration methods can be chained.

Examples

use std::thread;

let builder = thread::Builder::new()
                              .name("foo".into())
                              .stack_size(10);

let handler = builder.spawn(|| {
    // thread code
}).unwrap();

handler.join().unwrap();

Names the thread-to-be. Currently the name is used for identification only in panic messages.

The name must not contain null bytes (\0).

For more information about named threads, see this module-level documentation.

Examples

use std::thread;

let builder = thread::Builder::new()
    .name("foo".into());

let handler = builder.spawn(|| {
    assert_eq!(thread::current().name(), Some("foo"))
}).unwrap();

handler.join().unwrap();

Sets the size of the stack (in bytes) for the new thread.

The actual stack size may be greater than this value if the platform specifies minimal stack size.

For more information about the stack size for threads, see this module-level documentation.

Examples

use std::thread;

let builder = thread::Builder::new().stack_size(32 * 1024);

Spawns a new thread by taking ownership of the Builder, and returns an io::Result to its JoinHandle.

The spawned thread may outlive the caller (unless the caller thread is the main thread; the whole process is terminated when the main thread finishes). The join handle can be used to block on termination of the child thread, including recovering its panics.

For a more complete documentation see thread::spawn.

Errors

Unlike the spawn free function, this method yields an io::Result to capture any failure to create the thread at the OS level.

Panics

Panics if a thread name was set and it contained null bytes.

Examples

use std::thread;

let builder = thread::Builder::new();

let handler = builder.spawn(|| {
    // thread code
}).unwrap();

handler.join().unwrap();
