pub enum StackProtector {
    None,
    Basic,
    Strong,
    All,
}
Expand description

Controls use of stack canaries.

Variants§

§

None

Disable stack canary generation.

§

Basic

On LLVM, mark all generated LLVM functions with the ssp attribute (see llvm/docs/LangRef.rst). This triggers stack canary generation in functions which contain an array of a byte-sized type with more than eight elements.

§

Strong

On LLVM, mark all generated LLVM functions with the sspstrong attribute (see llvm/docs/LangRef.rst). This triggers stack canary generation in functions which either contain an array, or which take the address of a local variable.

§

All

Generate stack canaries in all functions.
