Enum rustc_target::spec::StackProtector

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

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.

Implementations

impl StackProtector

fn as_str(&self) -> &'static str

Trait Implementations

impl Clone for StackProtector

fn clone(&self) -> StackProtector

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StackProtector

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for StackProtector

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromStr for StackProtector

type Err = ()

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<StackProtector, ()>

Parses a string s to return a value of this type.

impl Hash for StackProtector

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<StackProtector> for StackProtector

fn eq(&self, other: &StackProtector) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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.
