# Struct std::thread::Builder 1.0.0 [−] [src]

    pub struct Builder { /* fields omitted */ }

Thread configuration. Provides detailed control over the properties and behavior of new threads.

## Methods

### `impl Builder`
[src]

#### `fn new() -> Builder`

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

#### `fn name(self, name: String) -> Builder`

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

# 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();Run

#### `fn stack_size(self, size: usize) -> Builder`

Sets the size of the stack for the new thread.

#### `fn spawn<F, T>(self, f: F) -> Result<JoinHandle<T>> where F: FnOnce() -> T, F: Send + 'static, T: Send + 'static`

Spawns a new thread, and returns a join handle for it.

The child thread may outlive the parent (unless the parent 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.

# Errors

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

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
