[Coil 3] Any future idea to migrate to kotlinx-io?

[revonateB0T]

Ktor is going to take kotlinx-io as their fundamental IO library.
https://youtrack.jetbrains.com/issue/KTOR-6030
And kotlinx-io will provide off-heap IO primitive support
Kotlin/kotlinx-io#239

Since platform image decoder is not written with Java/Kotlin (i.e. we will not parse image data within art/jvm heap), transfer them natively will be a good idea

Due to kotlinx-io is under development, I'm not expecting this to be implemented in few weeks(or months?)

No plans at the moment. Coil needs Okio's FileSystem class to read/write files to disk and I don't believe kotlinx-io has plans to add similar functionality soon.

Actually it looks like kotlinx-io has filesystems now! Going to look into this and chat with other folks to see what they think. My main concern is kotlinx-io is still under development so this might have to wait for Coil 4.x.

Yeah, land it in Coil 4.0 should be a fair choice

Looks like this'll be a Ktor 4.0 thing as well since it's not currently used in the 3.0 beta release. Coil will also migrate to kotlinx-io (likely in 4.0) once they give the go ahead for libraries to migrate to it.

We failed upgrade ktor without a new coil release.
