Trait PacketHeader 

pub trait PacketHeader: Sized {
    type InnerType;

    const NAME: &'static str;
    const FIXED_LEN: usize = _;

    // Required method
    fn inner_type(&self) -> Self::InnerType;

    // Provided methods
    fn total_len(&self, buf: &[u8]) -> usize { ... }
    fn is_valid(&self) -> bool { ... }
}

Required Associated Constants

const NAME: &'static str

Provided Associated Constants

const FIXED_LEN: usize = _

Required Associated Types

type InnerType

Required Methods

fn inner_type(&self) -> Self::InnerType

return the inner type of the header

Provided Methods

fn total_len(&self, buf: &[u8]) -> usize

Returns the length of the network layer header For protocols with variable-length headers (like IPv6 with extensions), the buffer is needed to calculate the correct length

fn is_valid(&self) -> bool

check whether the network layer header is valid

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
