枚举 OutboundChunks 

pub enum OutboundChunks<'a> {
    Single(&'a [u8]),
    Multiple {
        chunks: &'a [&'a [u8]],
        start: usize,
        end: usize,
    },
}

借用明文切片的集合

Warning: OutboundChunks does not guarantee that the simplest variant is 用. Multiple can hold non fragmented 或 empty payloads.

变体

Single(&'a [u8])

A single byte slice. Contrary 到 Multiple, this uses 一个 single pointer indirection

Multiple

A collection of chunks (byte slices) 并 cursors 到 single out 一个 fragmented range of bytes. OutboundChunks assumes that start <= end

字段

chunks: &'a [&'a [u8]]

start: usize

end: usize

实现

impl<'a> OutboundChunks<'a>

pub fn new(chunks: &'a [&'a [u8]]) -> Self

创建一个 payload 从 一个 slice of byte slices. If fragmented the cursors are added by default: start = 0, end = length

pub fn new_empty() -> Self

创建一个 payload with 一个 single empty slice

pub fn to_vec(&self) -> Vec<u8>

Flatten the slice of byte slices 到 an owned vector of bytes

pub fn copy_to_vec(&self, vec: &mut Vec<u8>)

Append all bytes 到 一个 vector

pub fn split_at(&self, mid: usize) -> (Self, Self)

Split self in two, around an index Works similarly 到 split_at in the core library, except it doesn’t panic if out of bound

pub fn is_empty(&self) -> bool

如果有效载荷为空，则返回 true

pub fn len(&self) -> usize

返回所有块的累计长度
