Crate kermit_derive 

Procedural macros for the Kermit workspace.

Provides #[derive(IntoTrieIter)] to automatically implement IntoIterator for trie-iterator types, wrapping them in TrieIteratorWrapper so that for tuple in iter { ... } yields Vec<usize> tuples directly.

Example

use kermit_iters::{LinearIterator, TrieIterator, TrieIteratorWrapper};
use kermit_derive::IntoTrieIter;

#[derive(IntoTrieIter)]
struct MyTrieIter<'a> {
    // ... fields ...
}

impl LinearIterator for MyTrieIter<'_> { /* ... */ }
impl TrieIterator   for MyTrieIter<'_> { /* ... */ }

// The derive generates:
//   impl<'a> IntoIterator for MyTrieIter<'a> {
//       type Item = Vec<usize>;
//       type IntoIter = TrieIteratorWrapper<Self>;
//       fn into_iter(self) -> Self::IntoIter { TrieIteratorWrapper::new(self) }
//   }

See kermit-derive/tests/derive_into_trie_iter.rs for a runnable example with a minimal mock trie, and kermit-ds for two production uses (TreeTrieIter, ColumnTrieIter).
