Struct HexWriter

pub struct HexWriter<T> { /* private fields */ }

Available on test or crate feature std only.

Given a T: fmt::Write, HexWriter implements std::io::Write and writes the source bytes to its inner T as hex characters.

Implementations

impl<T> HexWriter<T>

pub fn new(dest: T, case: Case) -> Self

Creates a HexWriter that writes the source bytes to dest as hex characters in the given case.

pub fn into_inner(self) -> T

Consumes this HexWriter returning the inner T.

Trait Implementations

impl<T> Write for HexWriter<T>

where T: Write,

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

Errors

If no bytes could be written to this HexWriter, and the provided buffer is not empty, returns std::io::ErrorKind::Other, otherwise returns Ok.

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

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.
