Enum entity::Filter

pub enum Filter {
    Id(TypedPredicate<Id>),
    Type(TypedPredicate<String>),
    Created(TypedPredicate<u64>),
    LastUpdated(TypedPredicate<u64>),
    Field(String, Predicate),
    Edge(String, Box<Filter>),
    IntoEdge(String),
}

Represents some filter to apply against an ent when searching through a database

Variants

Id(TypedPredicate<Id>)

Filters by the ent's id

Type(TypedPredicate<String>)

Filters by the ent's type

Created(TypedPredicate<u64>)

Filters by the ent's creation timestamp

LastUpdated(TypedPredicate<u64>)

Filters by the ent's last updated timestamp

Field(String, Predicate)

Filters by an ent's field

Edge(String, Box<Filter>)

Filters by an ent connected by an edge; not the same as Filter::IntoEdge, which converts an ent to its edge's ents

IntoEdge(String)

(Special case) Filters by converting an ent into the ents on its edge
