Struct IndentWriter 

pub struct IndentWriter<'buffer, W: Write> { /* private fields */ }

I/O-level indent writer.

Implementations

impl<'buffer, W: Write> IndentWriter<'buffer, W>

pub fn new(w: &'buffer mut W, indent: usize) -> Self

Constructs a new indent writer managing indents of indent spaces in the wrapped I/O buffer w.

pub fn with_raw_buffer<R, F: FnOnce(&mut W) -> R>(&mut self, f: F) -> R

Provides access to the wrapped I/O buffer in f.

Trait Implementations

impl<W: Write> IndentWriterCommon for IndentWriter<'_, W>

fn increase_indent(&mut self)

Adds a level of indentation. The new indent takes effect upon the next newline.

fn decrease_indent(&mut self)

Removes a level of indentation. The new indent takes effect upon the next newline.

fn indent_if_needed(&mut self)

You will usually not need to call this function manually.

impl<W: Write> Write for IndentWriter<'_, W>

fn write(&mut self, str: &[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, args: 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.
