Enum google_api_proto::google::devtools::cloudtrace::v2::span::SpanKind

#[repr(i32)]
pub enum SpanKind {
    Unspecified = 0,
    Internal = 1,
    Server = 2,
    Client = 3,
    Producer = 4,
    Consumer = 5,
}

Type of span. Can be used to specify additional relationships between spans in addition to a parent/child relationship.

Variants

Unspecified = 0

Unspecified. Do NOT use as default. Implementations MAY assume SpanKind.INTERNAL to be default.

Internal = 1

Indicates that the span is used internally. Default value.

Server = 2

Indicates that the span covers server-side handling of an RPC or other remote network request.

Client = 3

Indicates that the span covers the client-side wrapper around an RPC or other remote request.

Producer = 4

Indicates that the span describes producer sending a message to a broker. Unlike client and server, there is no direct critical path latency relationship between producer and consumer spans (e.g. publishing a message to a pubsub service).

Consumer = 5

Indicates that the span describes consumer receiving a message from a broker. Unlike client and server, there is no direct critical path latency relationship between producer and consumer spans (e.g. receiving a message from a pubsub service subscription).

Implementations

impl SpanKind

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of SpanKind.

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

👎Deprecated: Use the TryFrom<i32> implementation instead

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

impl SpanKind

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 SpanKind

fn clone(&self) -> SpanKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SpanKind

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

Formats the value using the given formatter.

impl Default for SpanKind

fn default() -> SpanKind

Returns the “default value” for a type.

impl From<SpanKind> for i32

fn from(value: SpanKind) -> i32

Converts to this type from the input type.

impl Hash for SpanKind

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 SpanKind

fn cmp(&self, other: &SpanKind) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for SpanKind

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

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl TryFrom<i32> for SpanKind

type Error = UnknownEnumValue

The type returned in the event of a conversion error.

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

Performs the conversion.
