Constant Summary collapse

VALID_CRYSTAL_TYPES =

Why Symbol is not included in VALID_CRYSTAL_TYPES? Because there is no way to convert String to Symbol. Symbols are translated to numbers in compile time. Use String instead of Symbol. See:

['Int8', 'Int8*', 'Array(Int8)',
'UInt8',   'UInt8*',   'Array(UInt8)',
'Int16',   'Int16*',   'Array(Int16)',
'UInt16',  'UInt16*',  'Array(UInt16)',
'Int32',   'Int32*',   'Array(Int32)',
'UInt32',  'UInt32*',  'Array(UInt32)',
'Int64',   'Int64*',   'Array(Int64)',
'UInt64',  'UInt64*',  'Array(UInt64)',
'Float32', 'Float32*', 'Array(Float32)',
'Float64', 'Float64*', 'Array(Float64)',
'String',
'Void'].freeze
