type Buffer: Default + AsRef<[Option<Self::Item>]> + AsMut<[Option<Self::Item>]>

Required Methods

fn collect_from_iter<I>(iter: I, buf: &mut Self::Buffer) -> Option<Self>

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.
