[][src]Struct tokio_io_pool::Builder

pub struct Builder { /* fields omitted */ }

Builds an I/O-oriented thread pool (Runtime) with custom configuration values.

Methods can be chained in order to set the configuration values. The thread pool is constructed by calling Builder::build. New instances of Builder are obtained via [Builder::default].

See function level documentation for details on the various configuration settings.

Methods

impl Builder[src]

pub fn pool_size(&mut self, val: usize) -> &mut Self[src]

Set the number of worker threads for the thread pool instance.

This must be a number between 1 and 32,768 though it is advised to keep this value on the smaller side.

The default value is the number of cores available to the system.

pub fn name_prefix<S: Into<String>>(&mut self, val: S) -> &mut Self[src]

Set name prefix of threads spawned by the scheduler

Thread name prefix is used for generating thread names. For example, if prefix is my-pool-, then threads in the pool will get names like my-pool-1 etc.

If this configuration is not set, then the thread will use the system default naming scheme.

pub fn after_start<F>(&mut self, f: F) -> &mut Self where
    F: Fn() + Send + Sync + 'static, 
[src]

Execute function f after each thread is started but before it starts doing work.

This is intended for bookkeeping and monitoring use cases.

pub fn before_stop<F>(&mut self, f: F) -> &mut Self where
    F: Fn() + Send + Sync + 'static, 
[src]

Execute function f before each thread stops.

This is intended for bookkeeping and monitoring use cases.

pub fn build(&self) -> Result<Runtime>[src]

Create the configured Runtime.

The returned Runtime instance is ready to spawn tasks.
