Struct il2_iltags::io::array::ByteArrayReader

pub struct ByteArrayReader<'a> { /* fields omitted */ }

ByteArrayReader implements a Reader that can extract bytes from a borrowed slice of bytes.

Implementations

impl<'a> ByteArrayReader<'a>

pub fn new(buff: &'a [u8]) -> ByteArrayReader<'a>

pub fn as_slice(&self) -> &[u8]

Returns a reference to the inner data as a slice.

pub fn can_read(&self, count: usize) -> Result<()>

Verifies if the specified number of bytes can be read from this struct.

Returns:

• Result(()): If it is possible to read the specified number of bytes;
• Result(ErrorKind::UnableToReadData): If it is not possible to read the specified number of bytes;

Trait Implementations

impl<'a> MemoryReader for ByteArrayReader<'a>

fn len(&self) -> usize

Returns the current size of the data.

fn offset(&self) -> usize

Returns the current offset of the data.

fn set_offset(&mut self, offset: usize)

Sets the current offset. If offset is larger than the length, it will set the offset to to the length of the data.

fn is_empty(&self) -> bool

Returns true if this reader is empty.

fn available(&self) -> usize

Returns the number of bytes available in the reader.

fn assert_can_read(&self, count: usize) -> Result<()>

This method verifies if a certain amount of bytes can be read/extracted.

impl<'a> Reader for ByteArrayReader<'a>

fn read(&mut self) -> Result<u8>

Reads a single byte from the source.

fn read_all(&mut self, buff: &mut [u8]) -> Result<()>

Reads the specified number of bytes from the source.

fn skip(&mut self, count: usize) -> Result<()>

Skips some bytes from the source.

fn skip_u64(&mut self, count: u64) -> Result<()>

Skips some bytes from the source using a u64 as its size. On 64-bit systems, this is equivalent to Self::skip() as usize is a 64-bit value.
