Struct opentelemetry::sdk::resource::Resource

pub struct Resource { /* fields omitted */ }

Describes an entity about which identifying information and metadata is exposed.

Items are sorted by key, and are only overwritten if the value is an empty string.

Implementations

impl Resource

pub fn new<T: IntoIterator<Item = KeyValue>>(kvs: T) -> Self

Create a new Resource from key value pairs.

Values are de-duplicated by key, and the first key-value pair with a non-empty string value will be retained

pub fn merge(&self, other: &Self) -> Self

Create a new Resource by combining two resources.

Keys from this resource have priority over keys from the merged resource.

pub fn len(&self) -> usize

Returns the number of attributes for this resource

pub fn is_empty(&self) -> bool

Returns true if the resource contains no attributes.

pub fn iter(&self) -> Iter

Gets an iterator over the attributes of this resource, sorted by key.

Trait Implementations

impl Clone for Resource

fn clone(&self) -> Resource

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Resource

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

Formats the value using the given formatter.

impl Default for Resource

fn default() -> Resource

Returns the "default value" for a type.

impl IntoIterator for Resource

type Item = (Key, Value)

The type of the elements being iterated over.

type IntoIter = IntoIter

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'a> IntoIterator for &'a Resource

type Item = (&'a Key, &'a Value)

The type of the elements being iterated over.

type IntoIter = Iter<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq<Resource> for Resource

fn eq(&self, other: &Resource) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Resource) -> bool

This method tests for !=.
