Struct Icmpv4MessageBuilder 

pub struct Icmpv4MessageBuilder<'a> { /* private fields */ }

Builds an ICMPv4 common header in caller-owned storage.

Implementations

impl<'a> Icmpv4MessageBuilder<'a>

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

Starts a builder for body_length bytes, which are left untouched.

pub fn message_type(self, value: Icmpv4Type) -> Self

Supplies the ICMPv4 message type.

pub fn code(self, value: u8) -> Self

Supplies the ICMPv4 message code.

pub fn build(self) -> Result<Icmpv4MessageMut<'a>, Icmpv4MessageBuildError>

Validates all inputs, writes the common header, and computes its complete checksum.

Body bytes and capacity beyond the requested message are preserved. On error, the whole caller-provided buffer is unchanged.
