Struct lexpr::Printer

pub struct Printer<W, F = DefaultFormatter> { /* fields omitted */ }

A printer for S-expression values.

Methods

impl<W> Printer<W, CustomizedFormatter> where
    W: Write, 

pub fn with_options(writer: W, options: Options) -> Self

Construct an S-expression printer tuned given the specified options.

impl<W, F> Printer<W, F> where
    W: Write,
    F: Formatter, 

pub fn with_formatter(writer: W, formatter: F) -> Self

Creates a new S-expression printer whose output will be written to the writer specified.

pub fn into_inner(self) -> W

Unwrap the Writer from the Printer.

pub fn print(&mut self, value: &Value) -> Result<()>

Output the representation of the specified value to the underlying writer.

impl<W> Printer<W> where
    W: Write, 

pub fn new(writer: W) -> Self

Creates a new S-expression printer.

Trait Implementations

impl<W: Debug, F: Debug> Debug for Printer<W, F>

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

Formats the value using the given formatter.

impl<W, F> Write for Printer<W, F> where
    W: Write, 

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

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

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

Flush 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 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

Creates a "by reference" adaptor for this instance of Write.
