[vlc-devel] [PATCH] Add Rust backed cue sheet parsing module

[Rémi Denis-Courmont]

Hi,

Either Rust is used as a special niche with its custom API, like Lua. Or it wraps (a relevant subset of) the plugin API.

It makes no sense to have to maintain dedicated glue code for each and every Rust module, especially if they're for the same VLC capability.
