Trait TryIteratorExt 

pub trait TryIteratorExt<T, E>: Iterator<Item = Result<T, E>> + Sized {
    // Provided methods
    fn try_map_while_and_collect<U, P, B>(self, predicate: P) -> B

Provided Methods

fn try_map_while_and_collect<U, P, B>(self, predicate: P) -> B

where P: FnMut(T) -> Option<U>, B: FromIterator<Result<U, E>>,

Tries to map and collect items from a fallible iterator, stopping early on the first error.

fn try_take_map_while_and_collect<U, F, P, B>( self, limit: Option<usize>, predicate: P, map_fn: F, ) -> Result<B, E>

where F: Fn(T) -> U, P: FnMut(&T) -> bool, B: FromIterator<U>,

Try taking at most limit items while predicate holds collecting mapped values and breaking early on errors.

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.
