E4095

Integer literal is out of range.

Integer literals can be used to initialize Byte, Int16, Int, Int64 and their unsigned variants. The range of these types are as follows:

Type	Minimum value	Maximum value
Byte	0	255
Int16	-32768	32767
UInt16	0	65536
Int	-2147483648	2147483647
UInt	0	4294967295
Int64	-9223372036854775808	9223372036854775807
UInt64	0	18446744073709551615

错误示例

fn main {
  let byte : Byte = 256
}

建议

You should either use a value that falls into the range of corresponding type, or adjust the type to accommodate the value.

fn main {
  let int : Int = 256
}
