Struct BlockingClient 

pub struct BlockingClient(/* private fields */);

A BonsaiDb client that blocks the current thread when performing requests.

Implementations

impl BlockingClient

pub fn build(url: Url) -> Builder<Blocking>

Returns a builder for a new client connecting to url.

pub fn new(url: Url) -> Result<Self, Error>

Initialize a client connecting to url. This client can be shared by cloning it. All requests are done asynchronously over the same connection.

If the client has an error connecting, the first request made will present that error. If the client disconnects while processing requests, all requests being processed will exit and return Error::Disconnected. The client will automatically try reconnecting.

The goal of this design of this reconnection strategy is to make it easier to build resilliant apps. By allowing existing Client instances to recover and reconnect, each component of the apps built can adopt a “retry-to-recover” design, or “abort-and-fail” depending on how critical the database is to operation.

pub fn send_api_request<Api: Api>( &self, request: &Api, ) -> Result<Api::Response, ApiError<Api::Error>>

Sends an api request.

pub fn invoke_api_request<Api: Api>(&self, request: &Api) -> Result<(), Error>

Sends an api request without waiting for a result. The response from the server will be ignored.

pub fn as_async(&self) -> &AsyncClient

Returns a reference to an async-compatible version of this client.

pub fn set_request_timeout(&mut self, timeout: impl Into<Duration>)

Sets this instance’s request timeout.

Each client has its own timeout. When cloning a client, this timeout setting will be copied to the clone.

Trait Implementations

fn clone(&self) -> BlockingClient

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BlockingClient

impl From<BlockingClient> for AsyncClient

fn from(client: BlockingClient) -> Self

Converts to this type from the input type.

impl HasSession for BlockingClient

fn session(&self) -> Option<&Session>

fn allowed_to<'a, R, P>(&self, resource_name: R, action: &P) -> bool

where R: AsRef<[Identifier<'a>]>, P: Action,

Checks if action is permitted against resource_name.

fn check_permission<'a, R, P>( &self, resource_name: R, action: &P, ) -> Result<(), Error>

where R: AsRef<[Identifier<'a>]>, P: Action,

impl StorageConnection for BlockingClient

type Authenticated = BlockingClient

The StorageConnection type returned from authentication calls.

type Database = BlockingRemoteDatabase

The type that represents a database for this implementation.

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

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

Deletes a database named name.

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>

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

where User: Nameable<'name, u64>,

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