Enum android_manifest::GwpAsanMode

pub enum GwpAsanMode {
    Never,
    Always,
}

GWP-ASan is a native memory allocator feature that helps find use-after-free and heap-buffer-overflow bugs.

Variants

Never

Always disabled: This setting completely disables GWP-ASan in your app and is the default for non-system apps.

Always

Always enabled: This setting enables GWP-ASan in your app, which includes the following:

1. The operating system reserves a fixed amount of RAM for GWP-ASan operations, approximately ~70KiB for each affected process. (Enable GWP-ASan if your app is not critically sensitive to increases in memory usage.)
2. GWP-ASan intercepts a randomly-chosen subset of heap allocations and places them into a special region that reliably detects memory safety violations.
3. When a memory safety violation occurs in the special region, GWP-ASan terminates the process.
4. GWP-ASan provides additional information about the fault in the crash report.

Trait Implementations

impl Clone for GwpAsanMode

fn clone(&self) -> GwpAsanMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GwpAsanMode

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

Formats the value using the given formatter.

impl Default for GwpAsanMode

fn default() -> GwpAsanMode

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for GwpAsanMode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<GwpAsanMode> for GwpAsanMode

fn eq(&self, other: &GwpAsanMode) -> 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.

impl Serialize for GwpAsanMode

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

Serialize this value into the given Serde serializer.

impl YaDeserialize for GwpAsanMode

fn deserialize<R: Read>(reader: &mut Deserializer<R>) -> Result<Self, String>

impl YaSerialize for GwpAsanMode

fn serialize<W: Write>(&self, writer: &mut Serializer<W>) -> Result<(), String>

fn serialize_attributes( &self, source_attributes: Vec<OwnedAttribute>, source_namespace: Namespace ) -> Result<(Vec<OwnedAttribute>, Namespace), String>
