Struct Slicer 

pub struct Slicer<'de> { /* private fields */ }

Takes a slice as input and divides it into smaller slices. For example &[1, 2, 3, 4] --> &[1, 2] and &[3, 4].

Uses:

• Used by MessageSlicer to help those implementing DecodeMessage’s from_bytes.
• When parsing formats within formats. For example, the DHCP format has an options field that contains TLV formatted options.

Implementations

impl<'de> Slicer<'de>

pub fn new(input: &'de [u8]) -> Self

Creates an instance of Slicer.

pub fn parse(&mut self, len: usize) -> Option<&'de [u8]>

Same as parse_unchecked, but returns Option instead of a panic.
