Overview
A fixed-size, stack allocated array.
StaticArray is a generic type with type argument T specifying the type of
its elements and N the fixed size. For example StaticArray(Int32, 3)
is a static array of Int32 with three elements.
Instantiations of this static array type:
StaticArray(Int32, 3).new(42) # => StaticArray[42, 42, 42]
StaticArray(Int32, 3).new { |i| i * 2 } # => StaticArray[0, 2, 4]
StaticArray[0, 8, 15] # => StaticArray[0, 8, 15]This type can also be expressed as Int32[3] (only in type grammar). A typical use
case is in combination with uninitialized:
ints = uninitialized Int32[3]
ints[0] = 0
ints[1] = 8
ints[2] = 15For number types there is also Number.static_array which can be used to initialize
a static array:
Int32.static_array(0, 8, 15) # => StaticArray[0, 8, 15]The generic argument type N is a special case in the type grammar as it
doesn't specify a type but a size. Its value can be an Int32 literal or
constant.
