Trait TryTools 

pub trait TryTools<T, E, S>
where
    S: TryStream<Ok = T, Error = E, Item = Result<T, E>> + ?Sized,
    Self: TryStream + Sized,
{
    // Required method
    fn try_take(
        self,
        n: usize,
    ) -> TryTakeWhile<Self, Ready<Result<bool, S::Error>>, impl FnMut(&S::Ok) -> Ready<Result<bool, S::Error>>>;
}

Adds general-purpose operations to fallible streams.

The adapters preserve the source error type and successful item order. They operate lazily without collecting the stream.

Required Methods

fn try_take( self, n: usize, ) -> TryTakeWhile<Self, Ready<Result<bool, S::Error>>, impl FnMut(&S::Ok) -> Ready<Result<bool, S::Error>>>

Limits the stream to at most n successful items.

After yielding n successes, the adapter consumes one additional success to detect the limit. Earlier source errors are still forwarded; with zero, they precede consumption of the first unyielded success.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
