Trait Reader 

pub trait Reader {
    // Required methods
    fn capacity(&self) -> usize;
    fn skip(&mut self, len: usize) -> Result<(), WriteTooLargeError>;
    fn write_to<W: Writer>(

        buf: BufMut<'_>,
    ) -> Result<(), WriteTooLargeError> { ... }
    fn write_to_slice(
        &mut self,
        buf: &mut [u8],
    ) -> Result<(), WriteTooLargeError> { ... }
}

An object from which bytes can be read.

Required Methods

fn capacity(&self) -> usize

Return the number of bytes that can still be read from self.

When the reader can generate arbitrary long output streams, usize::MAX is returned.

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

Skip over len bytes.

Errors

Errors when len > self.capacity().

fn write_to<W: Writer>( &mut self, writer: &mut W, n: usize, ) -> Result<(), WriteTooLargeError>

Write n bytes to writer.

Errors

Errors when n exceeds reader or writer capacity.

Provided Methods

fn write_to_buf(&mut self, buf: BufMut<'_>) -> Result<(), WriteTooLargeError>

Write buf.len() bytes of data into buf.

Errors

Errors when buf.len() exceeds reader capacity.

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

Write buf.len() bytes of data into buf.

Errors

Errors when buf.len() exceeds reader capacity.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
