Required Methods

fn summon_app_entry<ET>(&self) -> Result<ET, WasmError>

where ET: EntryTypesHelper, WasmError: From<<ET as EntryTypesHelper>::Error>,

Get the app entry that this action points to

Example: Basic Usage

use hdi::prelude::*;
use hdi_extensions::*;

#[hdk_entry_helper]
struct PostEntry {
    pub message: String,
}

#[hdk_entry_defs]
#[unit_enum(EntryTypesUnit)]
pub enum EntryTypes {
    #[entry_def]
    Post(PostEntry),
}

fn test(addr: ActionHash) -> ExternResult<()> {
    let action = summon_action( &addr )?.hashed.content;
    let entry_type = action.summon_app_entry<EntryTypes>()?;
    Ok(())
}

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
