Struct PropertySet 

pub struct PropertySet {
    pub entries: Vec<(String, PropertyValue)>,
}

A set of named properties attached to a metric. Order is preserved (it is significant on the wire, where keys and values are parallel arrays).

Fields

entries: Vec<(String, PropertyValue)>

The (key, value) entries, in wire order.

Implementations

impl PropertySet

pub fn new() -> Self

An empty property set.

pub fn with(self, key: impl Into<String>, value: PropertyValue) -> Self

Append a property, returning self for chaining.

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

Look up a property value by key (first match).

pub fn len(&self) -> usize

Number of properties.

pub fn is_empty(&self) -> bool

Whether the set is empty.

Trait Implementations

impl Clone for PropertySet

fn clone(&self) -> PropertySet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PropertySet

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

Formats the value using the given formatter.

impl Default for PropertySet

fn default() -> PropertySet

Returns the “default value” for a type.

impl PartialEq for PropertySet

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
