trait TextMapGetter[A]

Offers a way to get a string value associated with a given key.

A type class can be implemented for any data structure that stores key-value pairs.

Implicit instances of TextMapGetter are provided for scala.collection.Map and scala.collection.Seq types. The behavior of TextMapGetter[Seq[(String, String)]] when duplicate keys are present is unspecified, and may change at any time. In particular, if the behavior of Seq types with duplicate keys is ever specified by open telemetry, the behavior of such implicit instances will be made to match the specification.

Type parameters

A: the type of the key-value carrier

Abstract methods

Gets a string value from the carrier associated with the given key.

Value parameters

carrier: the carrier to get a value from
key: the key to get the value at

Attributes

Returns: a scala.Some if the key is present in carrier and scala.None otherwise
Source: TextMapGetter.scala

Returns a collection of all available keys in the given carrier.

Returns a collection of all available keys in the given carrier. The collection SHOULD never return duplicates.
