Struct pot::reader::SliceReader

pub struct SliceReader<'a> { /* private fields */ }

Reads data from a slice.

Implementations

impl<'a> SliceReader<'a>

pub const fn len(&self) -> usize

Returns the remaining bytes to read.

pub const fn is_empty(&self) -> bool

Returns true if there are no bytes remaining to read.

Trait Implementations

impl<'a> Debug for SliceReader<'a>

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

Formats the value using the given formatter.

impl<'a> From<&'a [u8]> for SliceReader<'a>

fn from(data: &'a [u8]) -> Self

Converts to this type from the input type.

impl<'a> From<SliceReader<'a>> for &'a [u8]

fn from(reader: SliceReader<'a>) -> Self

Converts to this type from the input type.

impl<'a> Read for SliceReader<'a>

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

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

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

Read the exact number of bytes required to fill buf.

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>

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

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

Read all bytes until EOF in this source, appending them to 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)

Read 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.

impl<'de> Reader<'de> for SliceReader<'de>

fn buffered_read_bytes( &mut self, length: usize, _scratch: &mut Vec<u8>, ) -> Result<BufferedBytes<'de>, Error>

Reads exactly length bytes.
