Trait nuts_bytes::TakeBytes

pub trait TakeBytes<'tb> {
    // Required method
    fn take_bytes(&mut self, n: usize) -> Result<Cow<'tb, [u8]>>;

    // Provided method
    fn take_bytes_to(&mut self, buf: &mut [u8]) -> Result<()> { ... }
}

Trait that describes a reader of binary data.

The Reader utility accepts all types that implements this trait.

Required Methods

fn take_bytes(&mut self, n: usize) -> Result<Cow<'tb, [u8]>>

Reads n bytes from the source.

If possible a slice of borrowed data of the given size (n) wrapped into Cow::Borrowed should be returned.

If the data cannot be borrowed a Vec<u8> wrapped into a Cow::Owned should be returned.

Errors

If not enough data are available an Error::Eof error is returned.

Provided Methods

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

Reads some bytes from the source and puts them into the given buffer buf.

Errors

If not enough data are available to fill buf an Error::Eof error is returned.

Implementations on Foreign Types

impl<'tb> TakeBytes<'tb> for &'tb [u8]

TakeBytes is implemented for &[u8] by taking the first part of the slice.

Note that taking bytes updates the slice to point to the yet unread part. The slice will be empty when EOF is reached.
