schematic_macros v0.17.8 (proc-macro) (*)

@hamracekk darling released a breaking change in a patch version.

However, this is fixed in 0.18.2.

[hamracekk]

Thank you for reply! The problem is that my project now depends on unstable feature.

error: failed to download `schematic_macros v0.18.2`

Caused by:
  unable to get packages from source

Caused by:
  failed to parse manifest at `/usr/local/cargo/registry/src/index.crates.io-6f17d22bba15001f/schematic_macros-0.18.2/Cargo.toml`

Caused by:
  feature `edition2024` is required

  The package requires the Cargo feature called `edition2024`, but that feature is not stabilized in this version of Cargo (1.84.0 (66221abde 2024-11-19)).
  Consider trying a newer version of Cargo (this may require the nightly release).
  See https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#edition-2024 for more information about the status of this feature.

Can't I use some lower stable version ?

[milesj]

@hamracekk You can try pinning darling in your Cargo.toml to a lower version and see if that works.

darling = "=0.20.10"
