Struct Request 

pub struct Request<'a> {
    pub kind: PacketType,
    pub seq_no: u16,
    pub cmd_id: u16,
    pub args: &'a [u8],
}

An RPC call from host to target.

The args field is a postcard-serialized argument struct. Its schema is identified by cmd_id, which encodes the function name and argument types as a hash (computed at firmware build time).

Fields

kind: PacketType

Packet kind — always PacketType::Request on the wire.

seq_no: u16

Monotonically increasing sequence number for matching responses to calls.

cmd_id: u16

Command identifier: hash of (function name + input schema + output schema).

args: &'a [u8]

Postcard-serialized argument bytes. Lifetime tied to the receive buffer.

Trait Implementations

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for Request<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de: 'a, 'a> Deserialize<'de> for Request<'a>

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> Serialize for Request<'a>

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,
