Struct HttpAdapter 

pub struct HttpAdapter { /* private fields */ }

HTTP adapter that talks to a remote CouchDB instance.

Implementations

impl HttpAdapter

pub fn new(url: &str) -> Self

Create a new HTTP adapter pointing at a CouchDB database URL.

The URL should include the database name, e.g. http://localhost:5984/mydb or http://admin:password@localhost:5984/mydb

pub fn with_client(url: &str, client: Client) -> Self

Create a new HTTP adapter with a custom reqwest client.

fn info<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<DbInfo>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Get database information: name, document count, update sequence.

fn get<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 str, opts: GetOptions, ) -> Pin<Box<dyn Future<Output = Result<Document>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Retrieve a single document by ID.

fn bulk_docs<'life0, 'async_trait>( &'life0 self, docs: Vec<Document>, opts: BulkDocsOptions, ) -> Pin<Box<dyn Future<Output = Result<Vec<DocResult>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Write multiple documents atomically.

fn all_docs<'life0, 'async_trait>( &'life0 self, opts: AllDocsOptions, ) -> Pin<Box<dyn Future<Output = Result<AllDocsResponse>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Retrieve a local document (not replicated, used for checkpoints).

fn put_local<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 str, doc: Value, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Write a local document (not replicated, used for checkpoints).

fn remove_local<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,
