pub(crate) struct ReprParser;Expand description
Parse #[repr(…)] forms.
Valid repr contents: any of the primitive integral type names (see
int_type_of_word, below) to specify enum discriminant type; C, to use
the same discriminant size that the corresponding C enum would or C
structure layout, packed to remove padding, and transparent to delegate representation
concerns to the only non-ZST field.
