Enum Pointer 

pub enum Pointer {
    FreshHeap,
    FreshStack,
    Unknown,
    StaticSingleton,
}

Describes what a returned pointer points to.

Variants

FreshHeap

Returns freshly allocated heap memory.

FreshStack

Returns freshly allocated stack memory.

Unknown

Returns unknown pointer.

StaticSingleton

Returns pointer to a static singleton (all calls return the same location).

Used for functions like __errno_location, getenv, gmtime, localtime that return pointers to internal static buffers. The abstract location is keyed by the callee function name, so multiple call sites to the same function share the same points-to target.

Trait Implementations

impl Clone for Pointer

fn clone(&self) -> Pointer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Pointer

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Pointer

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Pointer

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for Pointer

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Pointer
