derive_deftly_adhoc!() { /* proc-macro */ }Expand description
Expand an ad-hoc template, on a data structure decorated #[derive_deftly_adhoc]
use derive_deftly::{Deftly, derive_deftly_adhoc};
#[derive(Deftly)]
#[derive_deftly_adhoc]
struct DdtaStructureType { }
derive_deftly_adhoc! {
DdtaStructureType OPTIONS,..:
TEMPLATE
}Expands the template TEMPLATE for the type DdtaStructureType,
OPTIONS,.. is an optional comma-separated list of
expansion options.
The definition of DdtaStructureType must have been decorated
with #[derive(Deftly)],
and #[derive_deftly_adhoc],
and the resulting derive_deftly_driver_TYPE macro must be
available in scope.
derive_deftly_adhoc! can be used in any context
where the Rust language permits macro calls.
For example, it can expand to expressions, statements,
types, or patterns.
