Struct domain::base::opt::UnknownOptData

pub struct UnknownOptData<Octs> { /* private fields */ }

An OPT option in its raw form.

This type accepts any option type via its option code and raw data.

Implementations

impl<Octs> UnknownOptData<Octs>

pub fn new(code: OptionCode, data: Octs) -> Result<Self, LongOptData>

where Octs: AsRef<[u8]>,

Creates a new option from the code and data.

The function returns an error if data is longer than 65,535 octets.

pub unsafe fn new_unchecked(code: OptionCode, data: Octs) -> Self

Creates a new option data value without checking.

Safety

The caller needs to make sure that data is not longer than 65,535 octets.

pub fn code(&self) -> OptionCode

Returns the option code of the option.

pub fn data(&self) -> &Octs

Returns a reference for to the option data.

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

where Octs: AsRef<[u8]>,

Returns a slice of the option data.

pub fn as_slice_mut(&mut self) -> &mut [u8]

where Octs: AsMut<[u8]>,

Returns a mutable slice of the option data.
