bool pm_constant_pool_init(pm_constant_pool_t *pool, uint32_t capacity)
Initialize a new constant pool with a given capacity.
pm_constant_id_t pm_constant_pool_insert_shared(pm_constant_pool_t *pool, const uint8_t *start, size_t length)
Insert a constant into a constant pool that is a slice of a source string.
void pm_constant_id_list_init(pm_constant_id_list_t *list)
Initialize a list of constant ids.
unsigned int pm_constant_pool_bucket_type_t
The type of bucket in the constant pool hash map.
void pm_constant_id_list_free(pm_constant_id_list_t *list)

pm_constant_id_t pm_constant_pool_insert_constant(pm_constant_pool_t *pool, const uint8_t *start, size_t length)
Insert a constant into a constant pool from memory that is constant.
uint32_t pm_constant_id_t
A constant id is a unique identifier for a constant in the constant pool.
void pm_constant_id_list_insert(pm_constant_id_list_t *list, size_t index, pm_constant_id_t id)
Insert a constant id into a list of constant ids at the specified index.
bool pm_constant_id_list_append(pm_constant_id_list_t *list, pm_constant_id_t id)
Append a constant id to a list of constant ids.
pm_constant_id_t pm_constant_pool_insert_owned(pm_constant_pool_t *pool, uint8_t *start, size_t length)
Insert a constant into a constant pool from memory that is now owned by the constant pool.
static const pm_constant_pool_bucket_type_t PM_CONSTANT_POOL_BUCKET_OWNED
An owned constant is one for which memory has been allocated.
void pm_constant_id_list_init_capacity(pm_constant_id_list_t *list, size_t capacity)
