Length and capacity The built-in functions len and cap take arguments of various types and return a result of type int. The implementation guarantees that the result always fits into an int. Recall that int is either a 32- or 64-bit integer. So this means that the theoretical maximum length or capacity of the various types that support len and cap depends on the CPU architecture. However, this should not matter in practice, since you’d quickly exceed the available memory, before you had a s...
