Trait TryEnumerateExt 

pub trait TryEnumerateExt<Ok, Err>: Stream<Item = Result<Ok, Err>> + Sized {
    // Provided method
    fn try_enumerate(
        self,
    ) -> Map<Enumerate<Self>, fn((usize, Result<Ok, Err>)) -> Result<(usize, Ok), Err>> { ... }
}

Provided Methods

fn try_enumerate( self, ) -> Map<Enumerate<Self>, fn((usize, Result<Ok, Err>)) -> Result<(usize, Ok), Err>>

Like StreamExt::enumerate, but yields Result<(idx, ok), err>. See also TryEnumerateAllExt::try_enumerate_all() if you also want the count for Err results.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors
