Struct opentelemetry_api::resource::Resource

pub struct Resource<'a> {
    pub labels: HashMap<Cow<'a, str>, Cow<'a, str>>,
}

Fields

labels: HashMap<Cow<'a, str>, Cow<'a, str>>

Methods

impl<'a> Resource<'a>

pub fn create<K, V>(labels: HashMap<K, V>) -> Self where
    K: Into<Cow<'a, str>>,
    V: Into<Cow<'a, str>>, 

Creates a new Resource out of the collection of labels

Panics

If the following hold

• The length of a key or value is over 256 bytes
• If a key or value contains none ascii chars

pub fn merge(&mut self, other: Self)

Creates a new Resource that is a combination of labels of two Resources.

For example, from two Resources - one representing the host and one representing a container, resulting Resource will describe both.

Already set labels WILL NOT be overwritten unless they are empty string. Label key name-spacing SHOULD be used to prevent collisions across different resource detection steps.

pub fn labels(&self) -> HashMap<&str, &str>

pub fn get(&self, label: &str) -> Option<&str>

Helper method to get values for given labels

pub fn empty() -> Self
