example cannot find its own crate

[pdgilbert]

I was trying to change too much at once and it was shaking my sanity. Before attempting the compat layer I thought I would go back to a point I had working and try to put my example in my rust-radio-sx127x fork. So I branched just before "update everything" and have been trying to add it. But I cannot get the example code to find the modules of the crate it is in. I've tried referring to it as both radio_sx127x and as crate, and hundreds of other variations with no luck:

error[E0433]: failed to resolve: maybe a missing crate `radio_sx127x`?
  --> examples/lora_spi_send.rs:31:5
   |
31 | use radio_sx127x::{prelude::Error, prelude::Sx127x};
   |     ^^^^^^^^^^^^ maybe a missing crate `radio_sx127x`?

error[E0433]: failed to resolve: maybe a missing crate `device`?
  --> examples/lora_spi_send.rs:34:13
   |
34 | use crate::{device::lora::{LoRaConfig, LoRaChannel, Bandwidth, SpreadingFactor, CodingRate,
   |             ^^^^^^ maybe a missing crate `device`?

I've also tried adding it to its own Cargo.toml with no luck, and tried changing the directory name from rust-radio-sx127x to radio-sx127x just in case there was confusion between the crate name and the directory name, also with no luck.

The example does work outside the radio_sx127x crate as reported at https://pdgilbert.github.io/eg_stm_hal/#table-of-additional-examples-status and I have put examples in other crates, where I simply used use with the crate name like would be done normally to use it, and no need to add it to Cargo.toml.

Any suggestions?

Found the problem. Somehow edition = "2018" was missing in the Cargo.toml package section so external crate radio-sx127x was needed in the example code beforeuse. (The crate is considered external in the examples.)

ooof, that one is terrible / nice find! be good to add that edition keyword 😂

pros and cons of the type system eh. if you get stuck on things feel do free to keep posting em (or, email if it's not PRable), it's great to know where these abstractions work well and fail to hopefully improve em ^_^
