Struct ExtensionHeaders

pub struct ExtensionHeaders<'a> {
    pub hop_by_hop: Option<OptionsHeaderReader<'a>>,
    pub routing: Option<RoutingHeaderReader<'a>>,
    pub fragment: Option<FragmentHeaderReader<'a>>,
    pub auth_header: Option<AuthenticationHeaderReader<'a>>,
    pub destination_1st: Option<OptionsHeaderReader<'a>>,
    pub destination_2nd: Option<OptionsHeaderReader<'a>>,
    pub total_headers_len: usize,
    pub final_next_header: u8,
}

Contains all present extension headers in an IPv6 packet.

Each extension header is optional and should appear only once.

Except the Destination Options header, which may occur twice.

Fields

hop_by_hop: Option<OptionsHeaderReader<'a>>

routing: Option<RoutingHeaderReader<'a>>

fragment: Option<FragmentHeaderReader<'a>>

auth_header: Option<AuthenticationHeaderReader<'a>>

destination_1st: Option<OptionsHeaderReader<'a>>

destination_2nd: Option<OptionsHeaderReader<'a>>

total_headers_len: usize

final_next_header: u8

Implementations

impl<'a> ExtensionHeaders<'a>

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

Parses the extension headers from the given byte slice.

They are chained together through the next header field.

Thus, we need to loop through them all to run down the chain.

Trait Implementations

impl<'a> Debug for ExtensionHeaders<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
