Header content types.

The lowest 255 message types are reserved for cjdns/IPv6 packets. AKA: packets where the IP address is within the FC00::/8 block. Any packet sent in this way will have the IPv6 header deconstructed and this field will come from the next header field in the IPv6 header.

Cjdht

Bencoded inter-router DHT message

Iptun

Bencoded inter-router DHT message

Ctrl

This content type will never appear in the wild, it represents unencrypted control frames

Other

Unrecognized or user-defined content type.

If a message with unrecognized content type received, it is parsed as Other. Though if this message should be re-serialized and forwarded, the content type must be preserved. This should be done by other means, such as storing raw content type elsewhere.

Implementations

impl ContentType

pub const IP6_MAX: u32

The lowest 255 message types are reserved for cjdns/IPv6 packets

pub const RESERVED: u32

Reserved for future allocation

pub const RESERVED_MAX: u32

pub const AVAILABLE: u32

Content types in the AVAILABLE range are not defined and can be used like port numbers for subsystems of cjdns to communicate with subsystems within cjdns on other machines, providing they first agree on which numbers to use via CTRL messages

pub const MAX: u32

Maximum possible defined value for the content type

pub fn from_u16(code: u16) -> ContentType

pub fn try_to_u16(self) -> Option<u16>

Trait Implementations

impl Clone for ContentType

pub fn clone(&self) -> ContentType

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ContentType

impl Debug for ContentType

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

Formats the value using the given formatter.

impl Eq for ContentType

impl From<u32> for ContentType

pub fn from(number: u32) -> ContentType

Performs the conversion.

impl FromPrimitive for ContentType

type Primitive = u32

pub fn from_primitive(
    number: <ContentType as FromPrimitive>::Primitive
) -> ContentType

impl PartialEq<ContentType> for ContentType

pub fn eq(&self, other: &ContentType) -> bool

This method tests for self and other values to be equal, and is used by ==.
