Struct BoundedWriter

pub struct BoundedWriter { /* private fields */ }

Available on crate feature server only.

Bounded writer that allows writing at most max_len bytes.

   use std::io::Write;

   use jsonrpsee_core::server::helpers::BoundedWriter;

   let mut writer = BoundedWriter::new(10);
   (&mut writer).write("hello".as_bytes()).unwrap();
   assert_eq!(std::str::from_utf8(&writer.into_bytes()).unwrap(), "hello");

Implementations

impl BoundedWriter

pub fn new(max_len: usize) -> Self

Create a new bounded writer.

pub fn into_bytes(self) -> Vec<u8>

Consume the writer and extract the written bytes.

Trait Implementations

impl Clone for BoundedWriter

fn clone(&self) -> BoundedWriter

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BoundedWriter

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

Formats the value using the given formatter.

impl<'a> Write for &'a mut BoundedWriter

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

Writes a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flushes this output stream, ensuring that all intermediately buffered contents reach their destination.

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

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

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

Determines if this Writer has an efficient write_vectored implementation.

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

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

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

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, fmt: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

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

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.
