Trait Trunc 

pub trait Trunc
where
    Self: Sized,
{
    // Required method
    fn trunc(&mut self, len: usize);

    // Provided method
    fn clear(&mut self) { ... }
}

Truncate this collection to a new length.

If self was shorter than len, nothing happens.

If self was longer, drops elements up to len

Required Methods

fn trunc(&mut self, len: usize)

Provided Methods

fn clear(&mut self)

Erase all elements in the collection

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.
