    pub bytes: &'a [u8],
}

Fields

bytes: &'a [u8]

Implementations

impl<'a> OptionsHeaderReader<'a>

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

Creates a new OptionsHeaderReader from the given data slice.

pub fn next_header(&self) -> u8

Returns the next header field.

Specifies the type of the next header.

pub fn header_ext_len(&self) -> u8

Returns 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 options(&self) -> Result<&'a [u8], &'static str>

Returns the options and padding fields.

pub fn header_len(&self) -> usize

Returns the total header length in bytes.

pub fn header(&self) -> Result<&'a [u8], &'static str>

Returns a reference to the header.

May fail if the indicated header length exceeds the allocated buffer.

pub fn payload(&self) -> Result<&'a [u8], &'static str>

Returns a reference to the payload.

May fail if the indicated header length exceeds the allocated buffer.
