Trait FragmentedBuffer 

pub trait FragmentedBuffer {
    // Required methods
    fn len(&self) -> usize;
    fn with_bytes<'a, R, F>(&'a self, f: F) -> R
       where F: for<'b> FnOnce(FragmentedBytes<'b, 'a>) -> R;

    // Provided methods
    fn is_empty(&self) -> bool { ... }
    fn to_flattened_vec(&self) -> Vec<u8>  { ... }
}

A buffer that may be fragmented in multiple parts which are discontiguous in memory.

Required Methods

fn len(&self) -> usize

Gets the total length, in bytes, of this FragmentedBuffer.

fn with_bytes<'a, R, F>(&'a self, f: F) -> R

where F: for<'b> FnOnce(FragmentedBytes<'b, 'a>) -> R,

Invokes a callback on a view into this buffer’s contents as FragmentedBytes.

Provided Methods

fn is_empty(&self) -> bool

Returns true if this FragmentedBuffer is empty.

fn to_flattened_vec(&self) -> Vec<u8>

Returns a flattened version of this buffer, copying its contents into a Vec.

Dyn Compatibility

This trait is not dyn compatible.

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