Struct Rpc

pub struct Rpc {
    pub msg_type: RpcType,
    pub msg_id: RpcId,
    pub uid: u32,
    pub payload: Option<RpcPayload>,
}

See esp_hosted_rpc.proto.

Fields

msg_type: RpcType

E.g. send a request, and receive a response or event.

msg_id: RpcId

Identifies the type of message we’re sending.

uid: u32

This is used for tracking purposes; it can be anything we want. Responses will match it.

payload: Option<RpcPayload>

Notes: A: this is semi-redundant with msg_id. B: We currently only use it for responses and events, and maily for ones that have multiple records, which we’ve having a hard time parsing with micropb.

Implementations

impl Rpc

pub fn new_req(msg_id: RpcId, uid: u32) -> Self

pub fn to_bytes(&self, buf: &mut [u8], data: &[u8]) -> usize

Writes the Rpc struct and data to buf. Returns the total size used.

pub fn from_bytes(buf: &[u8]) -> Result<(Self, usize, usize), EspError>

Returns (Self, data start i, data len expected).

Trait Implementations

impl Format for Rpc

where RpcType: Format, RpcId: Format, Option<RpcPayload>: Format,

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.
