Struct zenoh::value::Value

#[non_exhaustive]pub struct Value {
    pub payload: ZBuf,
    pub encoding: Encoding,
}

Expand description

A zenoh Value.

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

§payload: ZBuf

The payload of this Value.

§encoding: Encoding

An encoding description indicating how the associated payload is encoded.

Implementations§

pub fn new(payload: ZBuf) -> Self

Creates a new zenoh Value.

pub fn empty() -> Self

Creates an empty Value.

pub fn encoding(self, encoding: Encoding) -> Self
