• flags: reserved for future use

Fields

magic: u32

Echo of the handshake magic.

protocol_version: u16

Server’s IPC protocol version.

status: u16

Handshake status code.

server_abi_major: u16

Server ABI major version.

server_abi_minor: u16

Server ABI minor version.

flags: u32

Reserved flags.

Implementations

impl IpcHandshakeReply

pub const fn ok() -> Self
