Struct TypedMap 

#[repr(C)]
pub struct TypedMap<K, V> {
    pub header: HeapHeader,
    pub buckets: *mut Bucket<K, V>,
    pub bucket_count: u32,
    pub len: u32,
    pub tombstone_count: u32,
    pub _pad: u32,
}

Typed open-addressing hash map with linear probing.

Fields

header: HeapHeader

buckets: *mut Bucket<K, V>

Pointer to bucket array.

bucket_count: u32

Number of buckets (always a power of 2).

len: u32

Number of live entries.

tombstone_count: u32

Number of tombstones.

_pad: u32

Implementations

impl<K: Copy, V: Copy> TypedMap<K, V>

pub fn new() -> *mut Self

Allocate a new empty TypedMap.

pub unsafe fn len(this: *const Self) -> u32

Number of entries.

Safety

this must point to a valid TypedMap.

pub unsafe fn is_empty(this: *const Self) -> bool

Whether the map is empty.

Safety

this must point to a valid TypedMap.

pub unsafe fn drop_map(ptr: *mut Self)

Deallocate the map and its bucket array.

Safety

ptr must point to a TypedMap allocated by this module.

impl<V: Copy> TypedMap<*const u8, V>

pub unsafe fn insert( this: *mut Self, key: *const StringObj, value: V, ) -> Option<V>

Insert a key-value pair. If the key already exists, updates the value and returns the old value.

The map retains the key pointer (caller must ensure it stays alive via refcounting). If the key already exists, the existing key pointer is kept.

Safety

this must point to a valid TypedMap. key must point to a valid StringObj.

pub unsafe fn get(this: *const Self, key: *const StringObj) -> Option<V>

Look up a value by string key.

Safety

this must point to a valid TypedMap. key must point to a valid StringObj.

pub unsafe fn contains_key(this: *const Self, key: *const StringObj) -> bool

Check if the map contains a key.

Safety

this must point to a valid TypedMap. key must point to a valid StringObj.

pub unsafe fn remove(this: *mut Self, key: *const StringObj) -> Option<V>

Remove a key from the map, returning the value if it was present.

Safety

this must point to a valid TypedMap. key must point to a valid StringObj.

impl<V: Copy> TypedMap<i64, V>

pub unsafe fn insert_i64(this: *mut Self, key: i64, value: V) -> Option<V>

Insert a key-value pair. If the key already exists, updates the value and returns the old value.

Safety

this must point to a valid TypedMap<i64, V>.

pub unsafe fn get_i64(this: *const Self, key: i64) -> Option<V>

Look up a value by i64 key.

Safety

this must point to a valid TypedMap<i64, V>.

pub unsafe fn contains_key_i64(this: *const Self, key: i64) -> bool

Check if the map contains an i64 key.

Safety

this must point to a valid TypedMap<i64, V>.

pub unsafe fn remove_i64(this: *mut Self, key: i64) -> Option<V>

Remove an i64 key from the map, returning the value if it was present.

Safety

this must point to a valid TypedMap<i64, V>.
