Trait kvarn_quinn_proto::BytesSource

pub trait BytesSource {
    // Required method
    fn pop_chunk(&mut self, limit: usize) -> (Bytes, usize);
}

A source of one or more buffers which can be converted into Bytes buffers on demand

The purpose of this data type is to defer conversion as long as possible, so that no heap allocation is required in case no data is writable.

Required Methods

fn pop_chunk(&mut self, limit: usize) -> (Bytes, usize)

Returns the next chunk from the source of owned chunks.

This method will consume parts of the source. Calling it will yield Bytes elements up to the configured limit.

The method returns a tuple:

• The first item is the yielded Bytes element. The element will be empty if the limit is zero or no more data is available.
• The second item returns how many complete chunks inside the source had had been consumed. This can be less than 1, if a chunk inside the source had been truncated in order to adhere to the limit. It can also be more than 1, if zero-length chunks had been skipped.
