Struct ezio::string::Writer

pub struct Writer(/* private fields */);

A writer for writing into a string (String).

Implements the Write trait, so this is a way to integrate strings into ezio’s trait system. Primarily designed for testing and other experimentation where proper IO is mocked with string data.

To access the written string data, convert into a String using into(), or get a reference using as_ref().

Trait Implementations

impl AsRef<str> for Writer

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Writer

fn clone(&self) -> Writer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Writer

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

Formats the value using the given formatter.

impl Into<String> for Writer

fn into(self) -> String

Converts this type into the (usually inferred) input type.

impl Write for Writer

fn write(&mut self, s: &str)

Write a string to self.

fn write_any(&mut self, o: impl ToString)

where Self: Sized,

Write any data which implements ToString to self.

impl Write for Writer

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

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

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

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 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.
