To support HTTPS endpoints, the async HTTP library `reqwest` needs one of
the `-tls` features enabled. While the users could specify this in their
own cargo dependencies, we here provide a new `esplora-async-https`
feature for conveinience.
We have some downstream folks who are using LDK in wasm compiled
via the normal rust wasm path. To ensure nothing breaks they want
to use `no-std` on the lightning crate, disabling time calls as
those panic. However, the HTTP logic in
`lightning-transaction-sync` gets automatically stubbed out by the
HTTP client crates when targeting wasm via `wasm_bindgen`, so it
works fine despite the std restrictions.
In order to make both work, `lightning-transaction-sync` can remain
`std`, but needs to not automatically enable the `std` flag on the
`lightning` crate, ie by setting `default-features = false`. We do
so here.
This crate provides utilities for syncing LDK via the transaction-based
`Confirm` interface. The initial implementation facilitates
synchronization with an Esplora backend server.
