结构体 ReadEarlyData 

pub struct ReadEarlyData<'a> { /* private fields */ }

允许在恢复的 TLS 1.3 连接中读取早期数据。

“Early data” 也 known as “0-RTT data”。

此结构体实现了 std::io::Read。

Trait 实现

impl Read for ReadEarlyData<'_>

fn read(&mut self, buf: &mut [u8]) -> Result<usize>

Pull some bytes from this source into the specified buffer, returning how many bytes were read. 更多信息

fn read_vectored(&mut self, bufs: &mut [IoSliceMut<'_>]) -> Result<usize, Error>

Like read, except that it reads into 一个 slice of buffers. 更多信息

fn is_read_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Reader has an efficient read_vectored implementation. 更多信息

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

Reads all bytes until EOF in this source, placing them into buf. 更多信息

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Reads all bytes until EOF in this source, appending them 到 buf. 更多信息

fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>

Reads the exact number of bytes required 到 fill buf. 更多信息

fn read_buf(&mut self, buf: BorrowedCursor<'_>) -> Result<(), Error>

🔬This is a nightly-only experimental API. (read_buf)

Pull some bytes 从 this source into the specified 缓冲区. 更多信息

fn read_buf_exact(&mut self, cursor: BorrowedCursor<'_>) -> Result<(), Error>

🔬This is a nightly-only experimental API. (read_buf)

Reads the exact number of bytes required 到 fill cursor. 更多信息

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates 一个 “by reference” adapter 用于 this instance of Read. 更多信息

fn bytes(self) -> Bytes<Self>

where Self: Sized,

Transforms this Read instance 到 an Iterator over its bytes. 更多信息

fn chain<R>(self, next: R) -> Chain<Self, R>

where R: Read, Self: Sized,

Creates an adapter which will chain this stream with another. 更多信息

fn take(self, limit: u64) -> Take<Self>

where Self: Sized,

Creates an adapter which will read at most limit bytes 从 it. 更多信息

fn read_array<const N: usize>(&mut self) -> Result<[u8; N], Error>

where Self: Sized,

🔬This is a nightly-only experimental API. (read_array)

Read 并 return 一个 fixed array of bytes 从 this source. 更多信息
