Trait SplitPrefix 

pub trait SplitPrefix<N>
where
    Self: Sized,
{
    type Prefix;

    // Required method
    fn split_prefix(self) -> Option<(Self::Prefix, Self)>;
}

Split off a number of elements from the beginning of the collection where the number is determined at compile time.

Required Associated Types

Required Methods

fn split_prefix(self) -> Option<(Self::Prefix, Self)>

Split N items from the beginning of the collection.

Return None if there are not enough items.

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.
