pub type c_char = i8;
Equivalent to C’s
char type is completely unlike Rust’s
char type; while Rust’s type represents a unicode scalar value, C’s
char type is just an ordinary integer. On modern architectures this type will always be either
u8, as they use byte-addresses memory with 8-bit bytes.
C chars are most commonly used to make C strings. Unlike Rust, where the length of a string is included alongside the string, C strings mark the end of a string with the character
CStr for more information.
