What makes Rust's enums so great?
variant and @practical-fp/union-types can get rid of that boilerplate as well. Disclaimer: I am the author of the latter.

Generic Object Type with similar parameters in TypeScript?
That's called a discriminating union type. I've made a small library to make discriminating unions easier to use. There also plenty of other excellent libraries like variant.

Help mapping JSON string to types
I've written a small library to get rid of most of the boilerplate required to use this pattern. It's however not the only library which does that. Also have a look at variant.

What makes Rust's enums so great?
FWIW, for TypeScript there are libraries such as ts-adt that help you skip over the boilerplate.

Rust Pattern Matching Examples for Typescript Developers
From a pattern matching perspective, Typescript is very limited in what it can do. Hence, this makes writing functional code more verbose and requires more boilerplate because you'll need to write your own matchers. See ts-adt as an example.
What are some alternatives?
When comparing union-types and ts-adt you can also consider the following projects:
