Macro hdk_crud::crud

macro_rules! crud {
    ($crud_type : ident, $i : ident, $path : expr, $get_peers : ident,
 $signal_type : ident) => { ... };
}

A macro to go quick and easy from having just a Holochain entry definition to having a full create-read-update-delete set of functionality in your Zome, “signals” (events), as well as time based indexing and queries. See example for a comprehensive look at how this works.

use hdk::prelude::*;
use hdk_crud::*;
#[hdk_entry(id = "example")]
#[derive(Clone, PartialEq)]
pub struct Example {
    pub number: i32,

// TestSignal pops out of the crud! macro
#[derive(Debug, Serialize, Deserialize, SerializedBytes)]
#[serde(untagged)]
pub enum SignalTypes {
Example(ActionSignal<Example>),

impl From<ActionSignal<Example>> for SignalTypes {
    fn from(value: ActionSignal<Example>) -> Self {
        SignalTypes::Example(value)
    }
}

pub fn recv_remote_signal(signal: ExternIO) -> ExternResult<()> {
    Ok(emit_signal(&signal)?)
}

pub fn get_peers() -> ExternResult<Vec<AgentPubKey>> {
    Ok(Vec::new())
}
