I find type byte byte very confusing in byte godoc , isn’t supposed to be type byte uint8 ?
byte is an alias for uint8 and is equivalent to uint8 in all ways. It is used, by convention, to distinguish byte values from 8-bit unsigned integer values. type complex128
分享 There is no real package builtin. But to explain the builtins a synthetic package builtin with synthetic types is generated for godoc. The type byte is never realy declared as type byte byte simply because byte is builtin and doesn't need a declaration. (And no byte is not and should not be declared as type byte uint8: byte is bultin and not declared.)
Just ignore the synthetic declarations and read the description. The description is the useful stuff here.
