Struct relay_dynamic_config::TagSpec

pub struct TagSpec {
    pub key: String,
    pub field: Option<String>,
    pub value: Option<String>,
    pub condition: Option<RuleCondition>,
}

Configuration for a tag to add to a metric.

Tags values can be static if defined through value or dynamically queried from the payload if defined through field. These two options are mutually exclusive, behavior is undefined if both are specified.

Fields

key: String

The key of the tag to extract.

field: Option<String>

Path to a field containing the tag’s value.

It follows the Getter syntax to read data from the payload.

Mutually exclusive with value.

value: Option<String>

Literal value of the tag.

Mutually exclusive with field.

condition: Option<RuleCondition>

An optional condition to meet before extraction.

See RuleCondition for all available options to specify and combine conditions. If no condition is specified, the tag is added unconditionally, provided it is not already there.

Implementations

impl TagSpec

pub fn source(&self) -> TagSource<'_>

Returns the source of tag values, either literal or a field.

Trait Implementations

impl Clone for TagSpec

fn clone(&self) -> TagSpec

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TagSpec

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TagSpec

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TagSpec

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
