Is Tokio actually required?

[John-Nagle]

I see a reference to Tokio in Cargo.toml, but not other references. Does Limbo actually need Tokio? I'd like to be able to run without it.

Limbo does not require Tokio.

Ref:

limbo/bindings/rust/Cargo.toml

Line 16 in 4a41736

tokio = { version = "1.29.1", features = ["full"] }

It’s dev dependency, not a normal dependency.

[dev-dependencies]
tokio = { version = "1.29.1", features = ["full"] }

vs.

[dependencies]
limbo_core = { path = "../../core" }

[dev-dependencies]s are used for unit/performance testing (for example) and are not build into lib or bin targets.

Yes, @John-Nagle, as @bwoods says, Tokio is used in the bindings/rust/examples/example.rs. However, even the Rust bindings are agnostic to Rust. They do use async but if that's too much, you can just use the core package, which is async-free. And sorry for the original short message, I was on my phone when I wrote it. 🙈
