Implementations

impl<'a> OptionsHeaderWriter<'a>

pub fn new(bytes: &'a mut [u8]) -> Result<Self, &'static str>

Creates a new OptionsHeaderWriter from the given data slice.

pub fn header_len(&self) -> usize

Returns the total Wheader length in bytes.

pub fn set_next_header(&mut self, next_header: u8)

Sets the next header field.

Specifies the type of the next header.

pub fn set_header_ext_len(&mut self, header_ext_len: u8)

Sets the header extension length field.

Length of the header in 8 bytes, not including the first 8 bytes.

E.g. Header length = (header_ext_len + 1) * 8.

pub fn set_options(&mut self, options: &[u8]) -> Result<(), &'static str>

Sets the options and padding fields.
