Struct KeySpec 

pub struct KeySpec {
    pub id: String,
    pub args: Vec<(String, ArgValue)>,
}

The key of one call: the entity id and any secondary dimensions.

Fields

id: String

The entity identifier, spelled as text.

args: Vec<(String, ArgValue)>

Secondary dimensions; absent values are dropped and names sorted when the key is built.

Implementations

impl KeySpec

pub fn new(id: impl IntoKeyId) -> Self

A key with id and no secondary dimensions. See IntoKeyId for the shared numeric spelling and supported input types.

pub fn arg(self, name: impl Into<String>, value: impl Into<ArgValue>) -> Self

Add a secondary key dimension. Absent values are omitted; names are sorted by UTF-16 code units when the key is built. Primitive integers preserve their exact decimal value; floats use JavaScript number spelling, with f32 promoted to f64. Shared references to supported inputs are also accepted.

Trait Implementations

impl Clone for KeySpec

fn clone(&self) -> KeySpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KeySpec

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

fn from(id: f64) -> Self

Converts to this type from the input type.

impl From<i8> for KeySpec

impl PartialEq for KeySpec

fn eq(&self, other: &KeySpec) -> 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.
