Trait il2_iltags::io::Reader[−][src]

pub trait Reader {
    fn read(&mut self) -> Result<u8>;

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

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

    fn skip_u64(&mut self, count: u64) -> Result<()> { ... }
}
Expand description

The Reader trait is allows the extraction of bytes from a source.

It differs from most IO library as it defines all operations as all-or-nothing operations. No partial reads are allowed.

Implementations of this trait are not required to be thread-safe.

Required methods

Reads a single byte from the source.

Returns:

  • Ok(v): The value read;
  • Err(ErrorKind): In case of error;

Provided methods

Reads the specified number of bytes from the source.

The default implementation just calls read() repeatedly, so each implementation is advised to provide a better implementation of this method if possible.

Arguments:

  • buff: The output buffer;

Returns:

  • Ok(()): On success;
  • Err(ErrorKind): In case of error;

Skips some bytes from the source.

The default implementation just calls read_all() repeatedly using 512 byte chunks. So it is recommended provide better implementations whenever possible.

Arguments:

  • count: Number of byte to skip;

Returns:

  • Ok(()): On success;
  • Err(ErrorKind): In case of error;

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.

This method will make a difference in 32-bit systems where usize is actually a 32-bit value.

This implementation calls Self::skip() as may times as necessary to skip the required number of bytes.

Arguments:

  • count: Number of byte to skip;

Returns:

  • Ok(()): On success;
  • Err(ErrorKind): In case of error;

New since 1.4.0.
