Implementations

impl IpcHandshake

pub const fn new() -> Self

Build a default handshake with a zero nonce.

pub const fn new_with_nonce(nonce: u32) -> Self

Build a handshake with a caller-provided nonce.

pub fn is_valid(&self) -> bool

Return true when the message carries the expected handshake magic.

pub fn is_compatible(&self) -> bool

Return true when magic and protocol version match this ABI.
