Derive Macro Topicable 

#[derive(Topicable)]
{
    // Attributes available to this derive:
    #[dds]
}

Derives Topicable for a named-field struct.

Fields annotated with #[dds(key)] are collected into a generated <Name>Key struct that implements CdrBounds. Structs with no #[dds(key)] fields use () as their key type and must implement [Default].

An optional #[dds(type_name = "...")] attribute overrides the DDS type name used for topic matching. Without it, the Rust type name is used.

Examples

#[derive(cyclonedds::Topicable, serde::Serialize, serde::Deserialize, Default, Clone, Debug)]
#[dds(type_name = "MySensor")]
pub struct Sensor {
    #[dds(key)]
    pub id: u32,
    pub value: f32,
}

// NOTE: this results in a hidden module being generated `__cyclonedds_topicable_Sensor`
// containing the following type: `Key { pub id: u32 }`

Panics

Panics at compile time if applied to an enum, a union, a tuple struct, or if #[dds(type_name)] is not a valid string literal.
