Enum Mode

#[repr(i32)]
pub enum Mode {
    Unspecified = 0,
    Active = 1,
    Generated = 2,
    Dump = 3,
    GeneratedBugreportOnly = 4,
}

Variants

Unspecified = 0

Active = 1

Trace layers snapshots. A snapshot is taken every time a layers change occurs.

Generated = 2

Generate layers snapshots from the transactions kept in the SurfaceFlinger’s internal ring buffer. The layers snapshots generation occurs when this data source is flushed.

Dump = 3

Trace a single layers snapshot.

GeneratedBugreportOnly = 4

Default mode (applied by SurfaceFlinger if no mode is specified). Same as MODE_GENERATED, but triggers the layers snapshots generation only when a bugreport is taken.

Implementations

impl Mode

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of Mode.

pub fn from_i32(value: i32) -> Option<Mode>

👎Deprecated: Use the TryFrom<i32> implementation instead

Converts an i32 to a Mode, or None if value is not a valid variant.

impl Mode

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

pub fn from_str_name(value: &str) -> Option<Self>

Creates an enum from field names used in the ProtoBuf definition.

Trait Implementations

impl Clone for Mode

fn clone(&self) -> Mode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Mode

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

Formats the value using the given formatter.

impl Default for Mode

fn default() -> Mode

Returns the “default value” for a type.

impl From<Mode> for i32

fn from(value: Mode) -> i32

Converts to this type from the input type.

impl Hash for Mode

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 Ord for Mode

fn cmp(&self, other: &Mode) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Mode

fn eq(&self, other: &Mode) -> 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 PartialOrd for Mode

fn partial_cmp(&self, other: &Mode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<i32> for Mode

type Error = DecodeError

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Mode, DecodeError>

Performs the conversion.

impl Copy for Mode

impl Eq for Mode

impl StructuralPartialEq for Mode
