pub struct ArpPacket<T: AsRef<[u8]>> { /* private fields */ }
Expand description
A read/write wrapper around an Address Resolution Protocol packet buffer.
Implementations§
source§impl<T: AsRef<[u8]>> Packet<T>
impl<T: AsRef<[u8]>> Packet<T>
sourcepub const fn new_unchecked(buffer: T) -> Packet<T>
pub const fn new_unchecked(buffer: T) -> Packet<T>
Imbue a raw octet buffer with ARP packet structure.
sourcepub fn new_checked(buffer: T) -> Result<Packet<T>>
pub fn new_checked(buffer: T) -> Result<Packet<T>>
Shorthand for a combination of new_unchecked and check_len.
sourcepub fn check_len(&self) -> Result<()>
pub fn check_len(&self) -> Result<()>
Ensure that no accessor method will panic if called.
Returns Err(Error)
if the buffer is too short.
The result of this check is invalidated by calling set_hardware_len or set_protocol_len.
sourcepub fn into_inner(self) -> T
pub fn into_inner(self) -> T
Consume the packet, returning the underlying buffer.
sourcepub fn hardware_type(&self) -> Hardware
pub fn hardware_type(&self) -> Hardware
Return the hardware type field.
sourcepub fn protocol_type(&self) -> Protocol
pub fn protocol_type(&self) -> Protocol
Return the protocol type field.
sourcepub fn hardware_len(&self) -> u8
pub fn hardware_len(&self) -> u8
Return the hardware length field.
sourcepub fn protocol_len(&self) -> u8
pub fn protocol_len(&self) -> u8
Return the protocol length field.
sourcepub fn source_hardware_addr(&self) -> &[u8] ⓘ
pub fn source_hardware_addr(&self) -> &[u8] ⓘ
Return the source hardware address field.
sourcepub fn source_protocol_addr(&self) -> &[u8] ⓘ
pub fn source_protocol_addr(&self) -> &[u8] ⓘ
Return the source protocol address field.
sourcepub fn target_hardware_addr(&self) -> &[u8] ⓘ
pub fn target_hardware_addr(&self) -> &[u8] ⓘ
Return the target hardware address field.
sourcepub fn target_protocol_addr(&self) -> &[u8] ⓘ
pub fn target_protocol_addr(&self) -> &[u8] ⓘ
Return the target protocol address field.
