Type Definition std::os::raw::c_char

pub type c_char = i8;

Equivalent to C’s char type.

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. This type will always be either i8 or u8, as the type is defined as being one byte long.

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 '\0'. See CStr for more information.
