Enum Type 

#[repr(i32)]
pub enum Type {
    Unspecified = 0,
    SliceBegin = 1,
    SliceEnd = 2,
    Instant = 3,
    Counter = 4,
}

Type of the TrackEvent (required if |phase| in LegacyEvent is not set).

Variants

Unspecified = 0

SliceBegin = 1

Slice events are events that have a begin and end timestamp, i.e. a duration. They can be nested similar to a callstack: If, on the same track, event B begins after event A, but before A ends, B is a child event of A and will be drawn as a nested event underneath A in the UI. Note that child events should always end before their parents (e.g. B before A).

Each slice event is formed by a pair of BEGIN + END events. The END event does not need to repeat any TrackEvent fields it has in common with its corresponding BEGIN event. Arguments and debug annotations of the BEGIN + END pair will be merged during trace import.

Note that we deliberately chose not to support COMPLETE events (which would specify a duration directly) since clients would need to delay writing them until the slice is completed, which can result in reordered events in the trace and loss of unfinished events at the end of a trace.

SliceEnd = 2

Instant = 3

Instant events are nestable events without duration. They can be children of slice events on the same track.

Counter = 4

Event that provides a value for a counter track. |track_uuid| should refer to a counter track and |counter_value| set to the new value. Note that most other TrackEvent fields (e.g. categories, name, ..) are not supported for TYPE_COUNTER events. See also CounterDescriptor.

Implementations

impl Type

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of Type.

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

👎Deprecated: Use the TryFrom<i32> implementation instead

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

impl Type

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<Type>

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

Trait Implementations

impl Clone for Type

fn clone(&self) -> Type

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Type

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

Formats the value using the given formatter.

impl Default for Type

fn default() -> Type

Returns the “default value” for a type.

impl Hash for Type

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

where __H: Hasher,

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 Type

fn cmp(&self, other: &Type) -> 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 Type

fn eq(&self, other: &Type) -> 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 Type

fn partial_cmp(&self, other: &Type) -> 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 Type

type Error = UnknownEnumValue

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Type, UnknownEnumValue>

Performs the conversion.

impl Copy for Type

impl Eq for Type

impl StructuralPartialEq for Type
