Range
Rather than using C style loop, in Rust, we use ..= to indicate a range:
Output:
Sequences are only allowed for numeric or character types because they can be consecutive.
Char
Use
''
. ""
is for the stringAccept
Unicode
, occupy 4 bytes.Bool
Only 1 byte.
Unit type
Literally, it is
()
.Yes, the unit type is
()
, and the value of this type is also, and only ()
.It's similar to
void
in other languages.Sometimes, you may come across code like
Result<(), String>
. This is an example of generic types in Rust. If you're familiar with C++ generic types, you can figure out that we pass 2 types into the Result
, regardless of what the Result
actually is.- Author:Parker Chen
