Struct SixlowpanExtHeaderRepr 

pub struct SixlowpanExtHeaderRepr {
    pub ext_header_id: ExtHeaderId,
    pub next_header: NextHeader,
    pub length: u8,
}

The fields of a 6LoWPAN NHC extension header.

The header has the following format (RFC 6282 § 4.2):

  0   1   2   3   4   5   6   7
+---+---+---+---+---+---+---+---+
| 1 | 1 | 1 | 0 |    EID    |NH |
+---+---+---+---+---+---+---+---+

An inline next header, if NH is clear, and the length follow it.

Fields

ext_header_id: ExtHeaderId

next_header: NextHeader

length: u8

The length of the payload, in bytes.

Implementations

impl ExtHeaderRepr

pub fn parse(buf: &[u8]) -> Result<(Self, usize)>

Parse a compressed extension header from the front of buf.

Returns the header and its length, not counting the payload.

Errors:

• Error if the buffer is shorter than the header, or does not start with an extension header dispatch.

pub const fn buffer_len(&self) -> usize

Return the length of the header this will emit, not counting the payload.

pub fn emit(&self, buf: &mut [u8])

Write the header into the front of buf.

Writes exactly buffer_len bytes.

Panics

Panics if buf is shorter than buffer_len.
