Struct diesel::query_builder::ValuesClause

source ·
pub struct ValuesClause<T, Tab> {
    pub values: T,
    /* private fields */
}
Available on crate feature i-implement-a-third-party-backend-and-opt-into-breaking-changes only.
Expand description

This type represents a values clause used as part of insert statements

Diesel exposes this type for third party backends so that they can implement batch insert support

Fields§

§values: T

Values to insert
