- Implement `pest_typed::TypedParser` for dervied struct.
- Generate several modules:
- `pairs`, which contains the definitions of some generated types. Each type corresponds to a rule.
- `constant_wrappers` and `rule_wrappers`, which contain some wrappers that are passed to predefined generics of statically typed nodes.
- `unicode`, which contains the definitions of Unicode-related built-in rules.
Only the first one is expected to be referenced by the user.
## Attributes
Attributes:
- Provide grammar file (see [pest.rs](https://pest.rs) and [its documents](https://docs.rs/pest/latest/pest/) for more information):
- `grammar`: specify grammar file path.
- `grammar_inline`: provide grammars in an inline string.
- Generation option:
| Attribute name | Default value | Meaning |
| :-----------------------------: | :-----------: | :-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------: |
| `emit_rule_reference` | false | Emit [accesser functions](#accesser-functions) for those rules referenced by current rule. |
| `emit_tagged_node_reference` | false | Emit [accesser functions](#accesser-functions) for those tagged nodes referenced by current rule. Only takes effect when node tags are enabled (currently controlled by feature **grammar-extras** of [pest](https://docs.rs/pest/latest/pest/)). |
| `do_not_emit_span` | false | Never emit field `span` for rules. |
| `truncate_accesser_at_node_tag` | true | Generated [accesser functions](#accesser-functions) won't contain those referenced rules or tags inside a tagged node. |
| `simulate_pair_api` | false | Generate implementation of Pair for rule structs |
See [pest_typed_derive](https://docs.rs/pest_typed_derive/latest/pest_typed_derive/) for more examples.
- Processing option:
- `no_warnings`: do not show warnings.
## Accesser functions
An accesser function is a function generated to access the referenced rules or tagged nodes.
Accesser function is named with the same name of the referenced rule or tag.
