Struct GetParameterTreeHashMsg

pub struct GetParameterTreeHashMsg {
    pub header: Option<Header>,
}

Request to get a parameter tree hash.

Instead of requesting a complete parameter tree, a client might request only a tree hash to compare it against the cached tree to detect if the tree on the server has been changed. The difference between hashes indicates the changes in the tree structure. Note: Changes in parameter values do not result in a different tree hash.

Server’s reply: ParameterTreeHashMsg, with following status codes:

StatusCode::OK - operation successful,

StatusCode::FAILED - operation failed.

StatusCode::FAILED_TO_DECODE - failed to decode request message.

Fields

header: Option<Header>

Frame counter and actual time.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

impl PartialEq for GetParameterTreeHashMsg

fn eq(&self, other: &GetParameterTreeHashMsg) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
