Struct breez_sdk_core::lightning::io::Sink

#[non_exhaustive]
pub struct Sink;

A writer which will move data into the void.

This struct is generally created by calling sink(). Please see the documentation of sink() for more details.

Trait Implementations

impl Clone for Sink

fn clone(&self) -> Sink

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Sink

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

Formats the value using the given formatter.

impl Default for Sink

fn default() -> Sink

Returns the “default value” for a type.

impl Write for &Sink

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

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

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

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

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.

impl Write for Sink

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

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

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.

impl WriteColor for Sink

fn supports_color(&self) -> bool

Returns true if and only if the underlying writer supports colors.

fn supports_hyperlinks(&self) -> bool

Returns true if and only if the underlying writer supports hyperlinks.

fn set_color(&mut self, _: &ColorSpec) -> Result<(), Error>

Set the color settings of the writer.

fn set_hyperlink(&mut self, _: &HyperlinkSpec<'_>) -> Result<(), Error>

Set the current hyperlink of the writer.

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

Reset the current color settings to their original settings.

fn is_synchronous(&self) -> bool

Returns true if and only if the underlying writer must synchronously interact with an end user’s device in order to control colors. By default, this always returns false.
