Overview ¶

Package pdata (pipeline data) implements data structures that represent telemetry data in-memory. All data received is converted into this format and travels through the pipeline in this format and that is converted from this format by exporters when sending.

Current implementation primarily uses OTLP ProtoBuf structs as the underlying data structures for many of of the declared structs. We keep a pointer to OTLP protobuf in the "orig" member field. This allows efficient translation to/from OTLP wire protocol. Note that the underlying data structure is kept private so that in the future we are free to make changes to it to make more optimal.

Most of internal data structures must be created via New* functions. Zero-initialized structures in most cases are not valid (read comments for each struct to know if it is the case). This is a slight deviation from idiomatic Go to avoid unnecessary pointer checks in dozens of functions which assume the invariant that "orig" member is non-nil. Several structures also provide New*Slice functions that allows to create more than one instance of the struct more efficiently instead of calling New* repeatedly. Use it where appropriate.

}

AnyValueArray logically represents a slice of AttributeValue.

This is a reference type, if passed by value and callee modifies it the caller will see the modification.

func (es AnyValueArray) Append(e AttributeValue)

Append will increase the length of the AnyValueArray by one and set the given AttributeValue at that new position. The original AttributeValue could still be referenced so do not reuse it after passing it to this method. Deprecated: Use AppendEmpty.

func (AnyValueArray) AppendEmpty ¶ added in v0.26.0

func (es AnyValueArray) At(ix int) AttributeValue

At returns the element at the given index.

This function is used mostly for iterating over all the values in the slice:

    e := es.At(i)
    ... // Do something with the element
}

func (AnyValueArray) CopyTo ¶ added in v0.9.0

func (es AnyValueArray) Resize(newLen int)

Resize is an operation that resizes the slice: 1. If the newLen <= len then equivalent with slice[0:newLen:cap]. 2. If the newLen > len then (newLen - cap) empty elements will be appended to the slice.

Here is how a new AnyValueArray can be initialized: es := NewAnyValueArray() es.Resize(4) 

for i := 0; i < es.Len(); i++ {
    e := es.At(i)
    // Here should set all the values for e.
}

	// contains filtered or unexported fields
}

Get returns the AttributeValue associated with the key and true. Returned AttributeValue is not a copy, it is a reference to the value stored in this map. It is allowed to modify the returned value using AttributeValue.Set* functions. Such modification will be applied to the value stored in this map.

If the key does not exist returns an invalid instance of the KeyValue and false. Calling any functions on the returned invalid instance will cause a panic.

func (AttributeMap) Len ¶ 

func (am AttributeMap) Len() int

Because the AttributeMap is represented internally by a slice of pointers, and the data are comping from the wire, it is possible that when iterating using "Range" to get access to fewer elements because nil elements are skipped.

func (AttributeMap) Range ¶ added in v0.25.0 

func (am AttributeMap) Range(f func(k string, v AttributeValue) bool)

  ...
})

type AttributeValue struct {
	// contains filtered or unexported fields
}

AttributeValue represents a value of an attribute. Typically used in AttributeMap. Must use one of NewAttributeValue+ functions below to create new instances.

Intended to be passed by value since internally it is just a pointer to actual value representation. For the same reason passing by value and calling setters will modify the original, e.g.: 

function f1(val AttributeValue) { val.SetIntVal(234) }
function f2() {
	v := NewAttributeValueString("a string")
   f1(v)
   _ := v.Type() // this will return AttributeValueTypeInt
