Functions to make it ergonomic to work with struct ASTs.
Required Methods§
Sourcefn data_struct(&self) -> &DataStruct
fn data_struct(&self) -> &DataStruct
Returns a reference to the data_struct of a struct’s AST.
§Panics
Panics if the AST is not for a struct.
Sourcefn data_struct_mut(&mut self) -> &mut DataStruct
fn data_struct_mut(&mut self) -> &mut DataStruct
Returns a mutable reference to the data_struct of a struct’s AST.
§Panics
Panics if the AST is not for a struct.
Sourcefn fields_mut(&mut self) -> &mut Fields
fn fields_mut(&mut self) -> &mut Fields
Returns a mutable reference to the fields of a struct’s AST.
§Panics
Panics if the AST is not for a struct.
Sourcefn fields_named(&self) -> &FieldsNamed
fn fields_named(&self) -> &FieldsNamed
Returns a mutable reference to the named fields of a struct’s AST.
§Panics
Panics if the AST is not for a struct with named fields.
Sourcefn fields_named_mut(&mut self) -> &mut FieldsNamed
fn fields_named_mut(&mut self) -> &mut FieldsNamed
Returns a mutable reference to the named fields of a struct’s AST.
§Panics
Panics if the AST is not for a struct with named fields.
Sourcefn assert_fields_unit(&self)
fn assert_fields_unit(&self)
Panics if the AST is not for a unit struct.
Sourcefn assert_fields_named(&self)
fn assert_fields_named(&self)
Panics if the AST is not for a struct with named fields.
Sourcefn assert_fields_unnamed(&self)
fn assert_fields_unnamed(&self)
Panics if the AST is not for a struct with unnamed fields.
