Span
A non owning view of contiguous data.
Parameters
- T (
CollectionElement): The type of the elements in the span. - is_mutable (
Bool): Whether the span is mutable. - lifetime (
lifetime<#lit.struct.extract<:_stdlib::_builtin::_bool::_Bool is_mutable, "value">>): The lifetime of the Span.

Methods
__init__
__init__(inout self: Self, *, unsafe_ptr: UnsafePointer[T, 0], len: Int)
Unsafe construction from a pointer and length.
Args:
- unsafe_ptr (
UnsafePointer[T, 0]): The underlying pointer of the span. - len (
Int): The length of the view.
__init__(inout self: Self, list: Reference[List[T], is_mutable, lifetime, 0])
Construct a Span from a List.
Args:
- list (
Reference[List[T], is_mutable, lifetime, 0]): The list to which the span refers.
__init__[size: Int](inout self: Self, array: Reference[InlineArray[T, size], is_mutable, lifetime, 0])
Construct a Span from an InlineArray.
Parameters:
- size (
Int): The size of the InlineArray.
Args:
- array (
Reference[InlineArray[T, size], is_mutable, lifetime, 0]): The array to which the span refers.
__getitem__
__getitem__(self: Self, idx: Int) -> ref [lifetime] T
Get a reference to an element in the span.
Args:
- idx (
Int): The index of the value to return.
Returns:
An element reference.
__getitem__(self: Self, slc: Slice) -> Self
Get a new span from a slice of the current span.
Args:
- slc (
Slice): The slice specifying the range of the new subslice.
Returns:
A new span that points to the same data as the current span.
unsafe_ptr
unsafe_ptr(self: Self) -> UnsafePointer[T, 0]
Gets a pointer to the first element of this slice.
Returns:
A pointer pointing at the first element of this slice.
