Struct Row 

pub struct Row<'a> {
    pub key: String,
    pub kinds: Vec<String>,
    pub property: Option<&'a str>,
}

One row asked for: the object (its full uri), its kind chain when it is a property, the property when it is.

Build it with Row::at from the object’s name: at is the one place that turns a name into the full identity the walk beneath (energyml_domain::color_walks) is keyed by, refusing a name that cannot say which of two versions is meant.

Fields

key: String

The object’s full uri, the key the walk beneath works in.

kinds: Vec<String>

For a property, its kind then the kind’s parents, nearest first.

property: Option<&'a str>

The property asked about, if the row is one.

Implementations

impl<'a> Row<'a>

pub fn at( store: &EpcStore, name: &str, kinds: Vec<String>, property: Option<&'a str>, ) -> Result<Self, Error>

The row of the object name names: a full uri (the form to pass), a short uri or a bare uuid (adapters, refused by name when the package holds the object in two versions and the name cannot say which). A name the package does not hold is walked as given: a cascade may ask about a target that lives elsewhere.
