Struct breez_sdk_liquid::lightning::util::ser::ReadTrackingReader

pub struct ReadTrackingReader<R>
where
    R: Read,
{
    pub have_read: bool,
    /* private fields */
}

A Read implementation which tracks whether any bytes have been read at all. This allows us to distinguish between “EOF reached before we started” and “EOF reached mid-read”.

This is not exported to bindings users as manual TLV building is not currently supported in bindings

Fields

have_read: bool

Returns whether we have read from this reader or not yet.

Implementations

impl<R> ReadTrackingReader<R>

where R: Read,

pub fn new(read: R) -> ReadTrackingReader<R>

Returns a new ReadTrackingReader.

Trait Implementations

impl<R> Read for ReadTrackingReader<R>

where R: Read,

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

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_vectored(&mut self, bufs: &mut [IoSliceMut<'_>]) -> Result<usize, Error>

Like read, except that it reads into a slice of buffers.

fn is_read_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Reader has an efficient read_vectored implementation.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

Reads all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Reads all bytes until EOF in this source, appending them to buf.

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

Reads the exact number of bytes required to fill buf.

fn read_buf(&mut self, buf: BorrowedCursor<'_>) -> Result<(), Error>

🔬This is a nightly-only experimental API. (read_buf)

Pull some bytes from this source into the specified buffer.

fn read_buf_exact(&mut self, cursor: BorrowedCursor<'_>) -> Result<(), Error>

🔬This is a nightly-only experimental API. (read_buf)

Reads the exact number of bytes required to fill cursor.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

where Self: Sized,

Transforms this Read instance to an Iterator over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R>

where R: Read, Self: Sized,

Creates an adapter which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

where Self: Sized,

Creates an adapter which will read at most limit bytes from it.
