Trait bounded_collections::TryCollect

pub trait TryCollect<C> {
    type Error;

    // Required method
    fn try_collect(self) -> Result<C, Self::Error>;
}

Try and collect into a collection C.

Required Associated Types

type Error

The error type that gets returned when a collection can’t be made from self.

Required Methods

fn try_collect(self) -> Result<C, Self::Error>

Consume self and try to collect the results into C.

This is useful in preventing the undesirable .collect().try_into() call chain on collections that need to be converted into a bounded type (e.g. BoundedVec).

Implementors

impl<I, K, V, Bound> TryCollect<BoundedBTreeMap<K, V, Bound>> for I

where K: Ord, I: ExactSizeIterator + Iterator<Item = (K, V)>, Bound: Get<u32>,

impl<I, T, Bound> TryCollect<BoundedBTreeSet<T, Bound>> for I

where T: Ord, I: ExactSizeIterator + Iterator<Item = T>, Bound: Get<u32>,

type Error = &'static str

impl<I, T, Bound> TryCollect<BoundedVec<T, Bound>> for I

where I: ExactSizeIterator + Iterator<Item = T>, Bound: Get<u32>,
