Struct async_executors::exec::TokioTpBuilder

pub struct TokioTpBuilder { /* private fields */ }

Builder to create a TokioTp executor. This guarantees that TokioTp always has a runtime that is multi-threaded, as tokio does not make this information available on it’s Runtime type.

Further allows you access to the tokio builder so you can set the other configuration options on it as you see fit.

Implementations

impl TokioTpBuilder

pub fn new() -> Self

Constructor.

pub fn tokio_builder(&mut self) -> &mut Builder

Returns the builder from tokio so you can configure it, see: Builder. If you mem::swap it, your warranty is void.

pub fn build(&mut self) -> Result<TokioTp, Error>

Create the actual executor.

The error comes from tokio. From their docs, no idea why it is there or what could go wrong. Suppose spawning threads could fail…
