Struct tx5::BackBuf

pub struct BackBuf { /* private fields */ }

Tx5 buffer type for sending and receiving data.

Implementations

impl BackBuf

pub fn from_slice<S: AsRef<[u8]>>(slice: S) -> Result<Self>

Build a tx5 buffer from a slice.

pub fn from_writer() -> Result<BackBufWriter>

Build a tx5 buffer using std::io::Write.

pub fn from_json<S: Serialize>(s: S) -> Result<Self>

Serialize a type as json into a new BackBuf.

pub fn len(&mut self) -> Result<usize>

Get the length of this buffer.

pub fn try_clone(&mut self) -> Result<Self>

Attempt to clone this buffer.

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

Copy the buffer out into a rust Vec<u8>.

pub fn to_json<D>(&mut self) -> Result<D>where D: DeserializeOwned + Sized,

Deserialize this buffer as json bytes into a type implementing serde::DeserializeOwned.

Trait Implementations

impl Debug for BackBuf

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'lt> From<&'lt mut BackBuf> for BackBufRef<'lt>

fn from(b: &'lt mut BackBuf) -> Self

Converts to this type from the input type.

impl From<BackBuf> for BackBufRef<'static>

fn from(b: BackBuf) -> Self

Converts to this type from the input type.

impl Read for BackBuf

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.

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

Like read, except that it reads into a slice of buffers.

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.

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

Read all bytes until EOF in this source, placing them into buf.

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

Read all bytes until EOF in this source, appending them to buf.

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

Read the exact number of bytes required to fill buf.

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

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

Pull some bytes from this source into the specified buffer.

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

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

Read the exact number of bytes required to fill cursor.

fn by_ref(&mut self) -> &mut Selfwhere Self: Sized,

Creates a “by reference” adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>where Self: Sized,

Transforms this Read instance to an Iterator over its bytes.

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

Creates an adapter which will chain this stream with another.

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

Creates an adapter which will read at most limit bytes from it.
