mention uniffi_macros = "*" in the rust book

[gogo2464]

since 0.23 uniffi_macros = "*" must be included in Cargo.toml with

[dependencies]
uniffi = {version = "", features = [ "cli" ]}
uniffi_macros = ""
uniffi_bindgen = "*"

in order to avoid a uniffi_bindgen build fail with:

error[E0425]: cannot find function uniffi_bindgen_main in crate uniffi
--> uniffi-bindgen.rs:2:13
|
2 | uniffi::uniffi_bindgen_main()
| ^^^^^^^^^^^^^^^^^^^ not found in uniffi

IT sounds necessary. Fell free to tell me if you have same issue. I may document it and be assigend in the issue if necessary.

I don't think that's true, eg, here's a Cargo.toml referencing 0.24 without any such requirement.

[gogo2464]

Strange. If you think so you may be right.

Also facing this with uniffi==0.24.3, adding uniffi_macros="*" did fix this.

@gogo2464 I have the same issue. PLEASE add this in the book

[gogo2464]

I may do this this week.

See above - uniffi_macros = "*" should not be needed, so we'd be unlikely to take a patch which recommends it without a detailed explanation which explains why it's not used either inside the repo or by Mozilla's use of the repo.

I don't see where this project calls uniffi_bindgen_main. In any case, the problem goes away if you include the "cli " feature (as explained in the docs).

Hello.

I am sorry that I did not do it yet. Do you still would like I do it? I could add it to the book REALLY this week if you like.

[hhanh00]

It is not necessary to have uniffi_macros="*" but you need features=["cli"] and the book mentions it on the command line of cargo run
