I've tried to write a function to replace string in a directory. And I founded a performance library written in Rust. https://github.com/TankerHQ/ruplacer, but the documentations only works in CLI. Now I can not custom the library to a function like that:
fn replace(path, foo, bar) {
ruplacer(path, foo, bar)
}

I know the file types .component, .service, .module, .guard., and no type just .ts
And i know .ts can have a type of --type=model.
And i know module can have --routing.
But what are the other ones? is there a resource for this?

I'm getting this on a match block:
patterns `&Unspecified` and `&__Nonexhaustive` not covered
The code:
fn vipaddress_from_ipddress(address: &IpAddress) -> VIpAddress {
match address {
I think &Unspecified has something to do with not accounting for null case, but references in Rust cannot be null. What is &__Nonexhaustive?
Seems to be an undocumented enum variant: https://docs.rs/ethox/0.0.1-wip/src/ethox/wire/ip.rs.html#15
This possibly indicates that the developer does not expect the users of IpAddress to match; maybe there is already a function doing what you want?

For example, I have a string like this
a = "starlight sunlight"
And I want to change it into
a = "starspot sunspot"
well i guessed you writing this in python so you can use the replace method
enter example
in your case you went to replace the word light with the word spot so just write
a=a.replace("light","post")
