Trait SetLen 

pub trait SetLen {
    // Required method
    unsafe fn set_len(&mut self, len: usize);
}

A helper trait for set_len like methods.

Required Methods

unsafe fn set_len(&mut self, len: usize)

Set the buffer length.

Safety

• len must be less or equal than as_uninit().len().
• The bytes in the range [buf_len(), len) must be initialized.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
