Minimum Supported Rust Version (MSRV) and the version of glib/gobject crates should be decided before being released.

In gtk-rs project, glib crate version 0.14 or later uses directory layout different from the previous releases for unknown reasons. It is preferable to use the same layout in hinawa crate.

In libhinawa, HinawaSndUnit has open method (=hinawa_snd_unit_open()) and derived objects override it by own method. However the overridden methods are missing from API crate as of hinawa-rs v0.1.0.

Affected objects and methods are:

• HinawaSndDg00x (hinawa_snd_dg00x_open)
• HinawaSndDice (hinawa_snd_dice_open)
• HinawaSndEfw (hinawa_snd_efw_open)
• HinawaSndMotu (hinawa_snd_motu_open)
• HinawaSndTscm (hinawa_snd_tscm_open)

Although sys crate generated by gtk/rs/gir includes the above, API crate doesn't. It's perhaps needed to write manual traits by hand. This requires user applications to rewrite the call of open methods specified to the overridden method since rustc cannot determine single trait from simple call of open method.

There is a plan to make future stable releases of libhinawa. It requires to publish new versions of hinawa Rust bindings.
