Trait TryExtend 

pub trait TryExtend {
    type Item;

    // Required method
    fn try_extend<Items>(&mut self, items: Items) -> Result<(), TryReserveError>
       where Items: IntoIterator<Item = Self::Item>;
}

Abstracts something which can try extend &mut self.

Required Associated Types

type Item

Item stocked in the collection

Required Methods

fn try_extend<Items>(&mut self, items: Items) -> Result<(), TryReserveError>

where Items: IntoIterator<Item = Self::Item>,

Used to expect a collection with an IntoIterator object.

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.
