Struct FieldMeta 

pub struct FieldMeta<'a>(/* private fields */);

Metadata for one AST field of one node type.

Use this to build generic inspectors, serializers, or debug UIs that can walk arbitrary grammars.

Implementations

impl FieldMeta<'_>

pub fn offset(&self) -> u16

Byte offset of this field within its parent AST node struct.

pub fn kind(&self) -> FieldKind

Semantic kind of this field.

pub fn name(&self) -> &'static str

The field name as a &str.

Panics

Panics if the grammar table contains invalid UTF-8 in the field name (which would indicate a codegen bug).

pub fn display_name(&self, idx: usize) -> Option<&'static str>

The idx-th display name for enum variants, if present.
