QueryBuilder

Struct QueryBuilder 

Source
pub struct QueryBuilder<E: QueryEngine, M: Model> { /* private fields */ }
Expand description

The main query builder that provides access to all query operations.

This is typically not used directly - instead, use the generated model accessors (e.g., client.user()).

Implementations§

Source§

Source

pub fn find_many(&self) -> FindManyOperation<E, M>

Start a find_many query.

Source

pub fn find_unique(&self) -> FindUniqueOperation<E, M>

Start a find_unique query.

Source

pub fn find_first(&self) -> FindFirstOperation<E, M>

Start a find_first query.

Source

pub fn create(&self) -> CreateOperation<E, M>

Start a create operation.

Source

pub fn update(&self) -> UpdateOperation<E, M>
