You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: coordinator.rs
    path of file: ./repos/holochain/crates/test_utils/wasm/wasm_workspace/crd/src
    
    the code of the file until where you have to start completion: use crate::integrity::*;
use hdk::prelude::*;

use EntryZomes::*;

#[hdk_dependent_entry_types]
enum EntryZomes {
    IntegrityCrd(EntryTypes),
}

#[hdk_extern]
fn create(_: ()) -> ExternResult<ActionHash> {
    create_entry(&IntegrityCrd(EntryTypes::Thing(Thing)))
}

/// `read` seems to be a reserved worked that causes SIGSEGV invalid memory reference when used as `#[hdk_extern]`
#[hdk_extern]
fn reed(action_hash: ActionHash) -> ExternResult<Option<Record>> {
    get(action_hash, GetOptions::network())
}

#[hdk_extern]
fn delete_via_hash(action_hash: ActionHash) -> ExternResult<ActionHash> {
    delete_entr
    
    fn delete_hash_smoke() {
        let mut mock_hdk = hdk::prelude::MockHdkT::new();

        let input_action_hash = fixt!(ActionHash);
        let output_action_hash = fixt!(ActionHash);
        let output_action_hash_closure = output_action_hash.clone();
        mock_hdk
            .expect_delete()
            .with(hdk::prelude::mockall::predicate::eq(DeleteInput::new(
                input_action_hash.clone(),
                ChainTopOrdering::default(),
            )))
            .times(1)
            .return_once(move |_| Ok(output_action_hash_closure));

        hdk::prelude::set_hdk(mock_hdk);

        let result = super::delete_via_hash(input_action_hash);

        assert_eq!(result, Ok(output_action_hash))
