Functions for interacting with a multi-database BonsaiDb instance.

Required Associated Types

type Database: Connection

The type that represents a database for this implementation.

type Authenticated: StorageConnection

The StorageConnection type returned from authentication calls.

Required Methods

fn admin(&self) -> Self::Database

Returns the administration database.

fn database<DB: Schema>(&self, name: &str) -> Result<Self::Database, Error>

Returns a reference to database name with schema DB.

fn create_database_with_schema( &self, name: &str, schema: SchemaName, only_if_needed: bool, ) -> Result<(), Error>

Creates a database named name using the SchemaName schema.

Errors

• Error::InvalidDatabaseName: name must begin with an alphanumeric character ([a-zA-Z0-9]), and all remaining characters must be alphanumeric, a period (.), or a hyphen (-).
• Error::DatabaseNameAlreadyTaken: name was already used for a previous database name. Returned if only_if_needed is false.

fn delete_database(&self, name: &str) -> Result<(), Error>

Deletes a database named name.

Errors

• Error::DatabaseNotFound: database name does not exist.
• Error::Other: an error occurred while deleting files.

fn list_databases(&self) -> Result<Vec<Database>, Error>

Lists the databases in this storage.

fn list_available_schemas(&self) -> Result<Vec<SchemaSummary>, Error>

Lists the SchemaNames registered with this storage.

fn create_user(&self, username: &str) -> Result<u64, Error>

Creates a user.

fn delete_user<'user, U: Nameable<'user, u64> + Send + Sync>( &self, user: U, ) -> Result<(), Error>

Deletes a user.

fn set_user_password<'user, U: Nameable<'user, u64> + Send + Sync>( &self, user: U, password: SensitiveString, ) -> Result<(), Error>

Sets a user’s password.

fn authenticate( &self, authentication: Authentication, ) -> Result<Self::Authenticated, Error>

Authenticates using the active session, returning a connection with a new session upon success. The existing connection will remain usable with the existing authentication, if any.

fn assume_identity( &self, identity: IdentityReference<'_>, ) -> Result<Self::Authenticated, Error>

Assumes the identity. If successful, the returned instance will have the permissions from identity.

fn add_permission_group_to_user<'user, 'group, U: Nameable<'user, u64> + Send + Sync, G: Nameable<'group, u64> + Send + Sync>( &self, user: U, permission_group: G, ) -> Result<(), Error>

Adds a user to a permission group.

fn remove_permission_group_from_user<'user, 'group, U: Nameable<'user, u64> + Send + Sync, G: Nameable<'group, u64> + Send + Sync>( &self, user: U, permission_group: G, ) -> Result<(), Error>

Removes a user from a permission group.

fn add_role_to_user<'user, 'role, U: Nameable<'user, u64> + Send + Sync, R: Nameable<'role, u64> + Send + Sync>( &self, user: U, role: R, ) -> Result<(), Error>

Adds a user to a permission group.

fn remove_role_from_user<'user, 'role, U: Nameable<'user, u64> + Send + Sync, R: Nameable<'role, u64> + Send + Sync>( &self, user: U, role: R, ) -> Result<(), Error>

Removes a user from a permission group.

Provided Methods

fn create_database<DB: Schema>( &self, name: &str, only_if_needed: bool, ) -> Result<Self::Database, Error>

Creates a database named name with the Schema provided.

Errors

• Error::InvalidDatabaseName: name must begin with an alphanumeric character ([a-zA-Z0-9]), and all remaining characters must be alphanumeric, a period (.), or a hyphen (-).
• Error::DatabaseNameAlreadyTaken: name was already used for a previous database name. Returned if only_if_needed is false.

fn authenticate_with_password<'name, User: Nameable<'name, u64>>( &self, user: User, password: SensitiveString, ) -> Result<Self::Authenticated, Error>

Authenticates a User using a password. If successful, the returned instance will have the permissions from identity.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
