Trait hdk::prelude::LinkTypeFilterExt

pub trait LinkTypeFilterExt {
    fn try_into_filter(self) -> Result<LinkTypeFilter, WasmError>;
}

An extension to obtain a link type filter.

Allows for single link types as well as the full range of link types to be passed in. To include all link types, i. e. not filter out any link type, the full range operator .. can be used: get_links(base, .., None).

Refer to the get_links function in this coordinator zome for several examples.
