Output Cargo.toml dependencies and features

[Emilgardis]

Should we have a way to make svd2rust output a [dependencies] and [features] given a set of arguments?

svd2rust cargo-toml --impl-defmt defmt -i STM32F30x.svd

would give

[dependencies]
critical-section = { version = "1.0", optional = true }
cortex-m = "0.7"
cortex-m-rt = { version = "0.7", optional = true }
vcell = "0.1"
defmt = { version = "0.3", optional = true }


[features]
rt = ["cortex-m-rt/device"]
defmt = ["dep:defmt"]

[Emilgardis]

This is partly motivated by #728 where I'd want this

[burrbull]

how you suggest to chose versions?

"*" ?

[burrbull]

maybe then some --init-crate name instead that creates full-featured crate which we can just cargo build?

[Emilgardis]

Yeah, I think using * in version could work, but there have been times (long time ago) where svd2rust didn't target latest release of a dependency. Doesn't happen often though, so * would be fine for me

[Emilgardis]

I don't think a full Cargo.toml is good enough, since the changes you would do to the toml file wouldn't persist between runs.
