Struct EthernetFrameBuilder 

pub struct EthernetFrameBuilder<'a> { /* private fields */ }

Ethernet II frame construction. Ethernet II frame construction. Ethernet II frame construction. An allocation-free builder for an Ethernet II header in a caller-provided buffer.

It writes the destination, source, and protocol-type header specified by RFC 894, never generates FCS bytes, and leaves the declared payload contents to the caller.

Implementations

impl<'a> EthernetFrameBuilder<'a>

pub fn new(buffer: &'a mut [u8], payload_length: usize) -> Self

Starts construction in buffer with an explicit payload length.

build will represent exactly the RFC 894 header followed by this many payload octets; it does not write payload and never generates FCS bytes.

pub fn destination(self, destination: MacAddress) -> Self

Supplies the destination address for the Ethernet header in RFC 894.

pub fn source(self, source: MacAddress) -> Self

Supplies the source address for the Ethernet header in RFC 894.

pub fn ether_type(self, ether_type: EtherType) -> Self

Supplies the protocol type for the Ethernet header in RFC 894.

pub fn build(self) -> Result<EthernetFrameMut<'a>, EthernetFrameBuildError>

Validates required fields and capacity, then writes exactly the Ethernet II header.

Validation completes before any write. On success, the returned view is restricted to the RFC 894 header plus the declared payload; payload and trailing capacity are unchanged, and FCS bytes are never generated.
