Functions
void	rdesc_stack_init (struct rdesc_stack **s)
	Initializes the token stack.
void	rdesc_stack_destroy (struct rdesc_stack *s)
	Frees memory allocated by the token stack.
void	rdesc_stack_push (struct rdesc_stack **s, struct rdesc_token tk)
	Pushes a token onto the stack.
struct rdesc_token	rdesc_stack_pop (struct rdesc_stack **s)
	Removes and returns the top token from the stack.
struct rdesc_token *	rdesc_stack_as_ref (struct rdesc_stack *s)
	Returns a reference to underlying dynamic buffer.
size_t	rdesc_stack_len (const struct rdesc_stack *s)
	Returns the underlying dynamic buffer.

Detailed Description

Token stack interface contract.

This header defines the function signatures required to manipulate the parser's backtracking stack.

Note

For custom implementations: If you have defined a custom struct rdesc_stack, you must provide implementations for all the functions declared in this file. The parser engine (librdesc) relies on these exact signatures to perform backtracking.
