Mojo struct

DictEntry

struct DictEntry[K: ExplicitlyCopyable & Movable & Hashable & EqualityComparable, V: ExplicitlyCopyable & Movable, H: Hasher]

Store a key-value pair entry inside a dictionary.

Parameters

K (ExplicitlyCopyable & Movable & Hashable & EqualityComparable): The key type of the dict. Must be Hashable+EqualityComparable.
V (ExplicitlyCopyable & Movable): The value type of the dict.
H (Hasher): The type of the hasher used to hash the key.

Fields

hash (SIMD[uint64, 1]): key.__hash__(), stored so hashing isn't re-computed during dict lookup.
key (K): The unique key for the entry.
value (V): The value associated with the key.

Implemented traits

AnyType, Copyable, ExplicitlyCopyable, Movable, UnknownDestructibility

Methods

`init`

__init__(out self, var key: K, var value: V)

Create an entry from a key and value, computing the hash.

Args:

key (K): The key of the entry.
value (V): The value of the entry.

`copyinit`

__copyinit__(out self, existing: Self)

Creates a copy of the given entry.

Args:

existing (Self): The entry to copy.

`reap_value`

reap_value(var self) -> V

Take the value from an owned entry.

Returns:

V: The value of the entry.
