Cant run in-process server in rust as per axum example

[danielblignaut]

Bug Report

I am running a Rust axum server and trying to launch an in-process perspective server in Rust (as per https://github.com/finos/perspective/blob/master/examples/rust-axum/src/main.rs )

The perspective crate in rust is the perspective-js crate, not the rust/perspective crate ( https://crates.io/crates/perspective ) so we have to point to the git version of the rust library, therefore we do the following below:

Steps to Reproduce:

1. have an existing rust workspace project
2. git clone https://github.com/finos/perspective
3. cd perspective
4. git checkout tkp/fixes
5. brew install cmake maturin
6. python -m venv perspective_venv
7. source perspective_venv/bin/activate
8. pip install jupyterlab
9. pnpm install
10. pnpm run build
11. in the root rust workspace project, edit Cargo.toml: perspective = { path = "./../perspective/rust/perspective" }
12. run cargo build

Expected Result:

Expect to be able to use the perspective rust library to start an in-process perspective server from Rust

Actual Result:

Various Failures:
