Struct DbSession 

pub struct DbSession<C: CanisterKind> { /* private fields */ }

DbSession database plus a debug boolean, as we don’t want to store the bool inside the database handle

Implementations

impl<C: CanisterKind> DbSession<C>

pub const fn new(db: Db<C>) -> Self

pub const fn debug(self) -> Self

pub const fn load<E>(&self) -> LoadExecutor<E>

where E: EntityKind<Canister = C>,

Get a LoadExecutor for building and executing queries that read entities.

pub const fn save<E>(&self) -> SaveExecutor<E>

where E: EntityKind<Canister = C>,

Get a SaveExecutor for inserting or updating entities.

Normally you will use the higher-level create/replace/update shortcuts instead.

pub const fn delete<E>(&self) -> DeleteExecutor<E>

where E: EntityKind<Canister = C>,

Get a DeleteExecutor for deleting entities by key or query.

pub fn insert<E>(&self, entity: E) -> Result<E, Error>

where E: EntityKind<Canister = C>,

pub fn replace<E>(&self, entity: E) -> Result<E, Error>

where E: EntityKind<Canister = C>,

pub fn update<E>(&self, entity: E) -> Result<E, Error>

where E: EntityKind<Canister = C>,

pub fn insert_view<E>(&self, view: E::ViewType) -> Result<E::ViewType, Error>

where E: EntityKind<Canister = C>,

pub fn replace_view<E>(&self, view: E::ViewType) -> Result<E::ViewType, Error>

where E: EntityKind<Canister = C>,

pub fn update_view<E>(&self, view: E::ViewType) -> Result<E::ViewType, Error>

where E: EntityKind<Canister = C>,
