Struct VssClient

pub struct VssClient<R>
where
    R: RetryPolicy<E = VssError>,
{ /* private fields */ }

Thin-client to access a hosted instance of Versioned Storage Service (VSS). The provided VssClient API is minimalistic and is congruent to the VSS server-side API.

Implementations

impl<R: RetryPolicy<E = VssError>> VssClient<R>

pub fn new(base_url: String, retry_policy: R) -> Self

Constructs a VssClient using base_url as the VSS server endpoint.

pub fn from_client(base_url: String, client: Client, retry_policy: R) -> Self

Constructs a VssClient from a given reqwest::Client, using base_url as the VSS server endpoint.

pub fn new_with_headers( base_url: String, retry_policy: R, header_provider: Arc<dyn VssHeaderProvider>, ) -> Self

Constructs a VssClient using base_url as the VSS server endpoint.

HTTP headers will be provided by the given header_provider.

pub fn base_url(&self) -> &str

Returns the underlying base URL.

pub async fn get_object( &self, request: &GetObjectRequest, ) -> Result<GetObjectResponse, VssError>

Fetches a value against a given key in request. Makes a service call to the GetObject endpoint of the VSS server. For API contract/usage, refer to docs for GetObjectRequest and GetObjectResponse.

pub async fn put_object( &self, request: &PutObjectRequest, ) -> Result<PutObjectResponse, VssError>

Writes multiple PutObjectRequest::transaction_items as part of a single transaction. Makes a service call to the PutObject endpoint of the VSS server, with multiple items. Items in the request are written in a single all-or-nothing transaction. For API contract/usage, refer to docs for PutObjectRequest and PutObjectResponse.

pub async fn delete_object( &self, request: &DeleteObjectRequest, ) -> Result<DeleteObjectResponse, VssError>

Deletes the given key and value in request. Makes a service call to the DeleteObject endpoint of the VSS server. For API contract/usage, refer to docs for DeleteObjectRequest and DeleteObjectResponse.

pub async fn list_key_versions( &self, request: &ListKeyVersionsRequest, ) -> Result<ListKeyVersionsResponse, VssError>

Lists keys and their corresponding version for a given ListKeyVersionsRequest::store_id. Makes a service call to the ListKeyVersions endpoint of the VSS server. For API contract/usage, refer to docs for ListKeyVersionsRequest and ListKeyVersionsResponse.

Trait Implementations

impl<R> Clone for VssClient<R>

where R: RetryPolicy<E = VssError> + Clone,

fn clone(&self) -> VssClient<R>

Returns a duplicate of the value.

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

Performs copy-assignment from source.
