Trait EntryTypesHelper 

pub trait EntryTypesHelper: Sized {
    type Error;

    // Required method
    fn deserialize_from_type<Z, I>(
        zome_index: Z,
        entry_def_index: I,
        entry: &Entry,
    ) -> Result<Option<Self>, Self::Error>
       where Z: Into<ZomeIndex>,
             I: Into<EntryDefIndex>;
}

Helper trait for deserializing Entrys to the correct type.

This is implemented by the hdk_entry_types proc_macro.

Required Associated Types

type Error

The error associated with this conversion.

Required Methods

fn deserialize_from_type<Z, I>( zome_index: Z, entry_def_index: I, entry: &Entry, ) -> Result<Option<Self>, Self::Error>

where Z: Into<ZomeIndex>, I: Into<EntryDefIndex>,

Check if the ZomeIndex and EntryDefIndex matches one of the ZomeEntryTypesKey::from(Self::variant) and if it does deserialize the Entry into that type.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
