Virtual table for a Map<String, T>

Fields

init: unsafe fn(ptr: *mut u8, size_hint: Option<usize>)

Initialize an empty map at the given pointer

insert: unsafe fn(_: *mut u8, key: Partial<'_>, value: Partial<'_>)

Insert a key-value pair into the map

len: unsafe fn(ptr: *const u8) -> usize

Get the number of entries in the map

contains_key: unsafe fn(ptr: *const u8, key: &str) -> bool

Check if the map contains a key

get_value_ptr: unsafe fn(ptr: *const u8, key: &str) -> *const u8

Get pointer to a value for a given key, returns null if not found

iter: unsafe fn(ptr: *const u8) -> *const u8

Get an iterator over the map

iter_vtable: MapIterVTable

Virtual table for map iterator operations

Trait Implementations

impl Clone for MapVTable

fn clone(&self) -> MapVTable

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MapVTable

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for MapVTable

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MapVTable

fn eq(&self, other: &MapVTable) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
