[−][src]Enum qualia::query_builder::QueryBuilder
A convenience class for creating QueryNode
objects. This enum should be used by calling
methods on Q
, rather than by creating a new QueryBuilder
yourself.
A QueryBuilder
starts out empty. Each call to .id()
, .equal()
, or .like()
will add a new criteria to the query. All these criteria are then ANDed together.
Implementations
impl QueryBuilder
[src]
pub fn id(self, value: impl Into<i64>) -> Self
[src]
Add the criteria that the object have the given ID.
pub fn equal(self, name: impl Into<String>, value: impl Into<PropValue>) -> Self
[src]
Add the criteria that the given field has exactly the given value.
pub fn like(self, name: impl Into<String>, pattern: impl Into<String>) -> Self
[src]
Add the criteria that the given field have contents matching the given value.
See PropLike
for the supported syntax.
pub fn build(self) -> QueryNode
[src]
Consume this QueryBuilder
and build a QueryNode
.
