1//! JMAP Tasks extension client methods.
2//!
3//! # Usage
4//!
5//! ```rust,no_run
6//! # use jmap_tasks_client::JmapTasksExt;
7//! # async fn example(client: jmap_base_client::JmapClient) -> Result<(), jmap_base_client::ClientError> {
8//! let session = client.fetch_session().await?;
9//! let sc = client.with_tasks_session(session);
10//! let task_lists = sc.task_list_get(None, None).await?;
11//! # Ok(())
12//! # }

29/// Extension trait adding JMAP Tasks methods to [`jmap_base_client::JmapClient`].
30///
31/// Import this trait to use: `use jmap_tasks_client::JmapTasksExt;`
32/// This trait is **sealed**: implementations outside this crate are not
33/// permitted. The crate adds an `impl` only for
34/// [`jmap_base_client::JmapClient`]. Sealing prevents downstream
35/// divergence (e.g. `impl JmapTasksExt for MySimulator`) and keeps
36/// adding methods to the trait a non-breaking change.

38    /// Bind this client to a JMAP session for use with Tasks methods.
39    ///
40    /// The returned [`SessionClient`] captures the session at construction time.
41    /// After re-fetching the session, construct a new `SessionClient` with the
42    /// updated session.
43    ///
44    /// # Deferred session-capability validation
45    ///
46    /// This constructor accepts ANY [`jmap_base_client::Session`],
47    /// including one whose advertised capabilities do not include
48    /// `urn:ietf:params:jmap:tasks` or whose `primaryAccounts` map has
49    /// no entry for the tasks capability. The constructor performs no
50    /// up-front validation and never fails — its return type is the
51    /// infallible [`methods::SessionClient`], not a `Result`.
52    ///
53    /// Capability and primary-account validation is deferred to every
54    /// individual method call on the returned [`SessionClient`]. If
55    /// the session is unsuitable, those per-method calls return
56    /// [`ClientError::InvalidSession`] with a description like
57    /// `"no primary account for urn:ietf:params:jmap:tasks"`.
58    ///
59    /// Callers that want to guard at the binding site can pre-check
60    /// the session before calling this method via
61    /// [`session.primary_account_id("urn:ietf:params:jmap:tasks")`](jmap_base_client::Session::primary_account_id).
