CRUD

Create

Create resource, which the server assigns an id to and creates. In Gleam, patient_create (or any resource) returns an Ok(Patient) or error.

Read

Read resource by id. In Gleam, patient_read (or any resource) returns an Ok(Patient) or error.

Update

Update resource on server to be sent resource (by id, which is required in sent resource). If server allows client defined ids, update can be used to create a new resource on server at specific id (vs create, which lets the server assign id). In Gleam, patient_update (or any resource) returns an Ok(Patient) or error.

Delete

Delete resource on server (by id, which is required in sent resource). In Gleam, patient_delete (or any resource), no matter what type of resource is deleted, returns Ok(Operationoutcome) or an http status indicating success (on success, servers may send back an OperationOutcome but may also send only http status with empty body), or error.
