Constructor Details

#initialize(size_or_values, packed = false, context = nil, &block) {|index| ... } ⇒ ConstantStruct

Create a new constant struct value.

Examples:

Using array of values:

ConstantStruct.new([Int32.new(0), Int64.new(1), Int32.new(2), Int64.new(3)])

Using size:

ConstantStruct.new(4) { |i| if i % 2 == 0 then Int32.new(i) else Int64.new(i) end }

Yield Parameters:

  • index (Integer) —

    Index of the value in the struct.
