[−][src]Struct ejdb::query::QH
An entry point for constructing query hints.
This is a convenience API. This structure provides the same methods as QueryHints
structure and inside them a fresh QueryHints instance is created and the corresponding
method is called on it. This is the main approach for constructing query hints.
Example
use ejdb::query::{QueryHints, QH}; assert_eq!( QueryHints::new().max(128).field("name").include().order_by("date").desc(), QH.max(128).field("name").include().order_by("date").desc() )
Methods
impl QH[src]
pub fn empty(self) -> QueryHints[src]
pub fn max(self, n: i64) -> QueryHints[src]
pub fn skip(self, n: i64) -> QueryHints[src]
pub fn order_by<S: Into<String>>(self, field: S) -> QueryHintsOrderBy[src]
pub fn field<S: Into<String>>(self, field: S) -> QueryHintsField[src]
