[drahnr]

Developing cargo-spellcheck which utilizes ra_ap_syntax, the compilation fails with anything after 0.0.42.

Which version of rowan does Cargo.lock state?

[drahnr]

[[package]]
name = "rowan"
version = "0.13.0-pre.5"
source = "registry+https://github.com/rust-lang/crates.io-index"
checksum = "32a5fc82ed0b7e7fba157331f0d8f64abd73bced6e7ac2a4dfa0c4cf0ab584e8"
dependencies = [
 "countme",
 "hashbrown",
 "memoffset",
 "rustc-hash",
 "text-size",
]

[bjorn3]

Rust-analyzer's Cargo.lock states version 0.13.0-pre.3. Maybe there was a breaking change? Try downgrading to this version. For example by editing the version field and removing the checksum field.

[drahnr]

That works :)

rowan 0.13 is out, I don't think there's anything left to do here.
