Enum IndexScope 

pub enum IndexScope {
    Table {
        table: String,
        column: String,
    },
    Graph {
        collection: String,
    },
    Timeseries {
        series: String,
    },
}

Implementations

impl IndexScope

pub fn table(table: impl Into<String>, column: impl Into<String>) -> IndexScope

Build a table-scoped key.

pub fn graph(collection: impl Into<String>) -> IndexScope

Build a graph-scoped key.

pub fn timeseries(series: impl Into<String>) -> IndexScope

Build a timeseries-scoped key.

Trait Implementations

impl Clone for IndexScope

fn clone(&self) -> IndexScope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IndexScope

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

Formats the value using the given formatter.

impl Hash for IndexScope

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for IndexScope

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