pub type c_char = i8;Expand description
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. On modern architectures this type will always be either i8 or 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 '\0'. See CStr for more information.
Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
