pub struct Attribute {
    pub field: Option<Field>,
    pub unit: Option<String>,
}
Expand description

State attributes of an entity. These are dependent on the type of the entity.

For example, a timer resource will have a duration, while a semaphore resource may have a permit count. Likewise, the async ops of a semaphore may have attributes indicating how many permits they are trying to acquire vs how many are acquired. These values may change over time. Therefore, they live in the runtime stats rather than the static data describing the entity.

Fields

field: Option<Field>

The key-value pair for the attribute

unit: Option<String>

Some values carry a unit of measurement. For example, a duration carries an associated unit of time, such as “ms” for milliseconds.

Implementations
