Summary

All PR CI builds are failing with a Rust type mismatch error in the llama-cpp-2 crate during buildRustNativesForHost.

Error

error[E0308]: mismatched types
  --> /home/ci-agent/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/llama-cpp-2-0.1.126/src/lib.rs:416:35

    |                    -------------- ^^^^^^^^^^ expected `*const i8`, found `*const u8`

Similar errors at lines 417 and 420 for description and backend_name.

Affected PRs

• feat(js): support nested conditional exports in package.json #1794 (run 19686807280)
• feat/crypto-random-int (run 19684791019)

Main branch runs show as "skipped" so they don't hit this path.

Possible Causes

1. Rust toolchain update on CI runners changed c_char type definition
2. llama-cpp-2 crate version 0.1.126 incompatible with current toolchain
3. CI runner environment changed
