retina_core::protocols::packet::ipv6

Struct Ipv6

Source
pub struct Ipv6<'a> { /* private fields */ }
Expand description

An IPv6 packet.

Optional IPv6 extension headers are not parsed by default.

Implementations§

Source

pub fn flow_label(&self) -> u32

Returns the flow label.

Source

pub fn version_to_flow_label(&self) -> u32
