struct ListLiteral[*Ts: CollectionElement]

The type of a literal heterogeneous list expression.

A list consists of zero or more values, separated by commas.

Parameters​

  • ​*Ts (CollectionElement): The type of the elements.

Fields​

  • ​storage (Tuple[Ts]): The underlying storage for the list.

Implemented traits​

AnyType, CollectionElement, Copyable, Movable, Sized, UnknownDestructibility

Methods​

__init__​

__init__(out self, owned *args: *Ts)

Construct the list literal from the given values.

Args:

  • ​*args (*Ts): The init values.

__copyinit__​

__copyinit__(out self, existing: Self)

Copy construct the tuple.

Args:

  • ​existing (Self): The value to copy from.

__moveinit__​

__moveinit__(out self, owned existing: Self)

Move construct the list.

Args:

  • ​existing (Self): The value to move from.

__contains__​

__contains__[T: EqualityComparableCollectionElement](self, value: T) -> Bool

Determines if a given value exists in the ListLiteral.

Parameters:

  • ​T (EqualityComparableCollectionElement): The type of the value to search for. Must implement the EqualityComparable trait.
