The main crate still has dependency issues but the foundation for stable compilation has been established. ### Files Modified: - dev-deps/data-rs/src/lib.rs (removed unstable features) - dev-deps/data-rs/src/link_type.rs (removed const/~const) - dev-deps/data-rs/src/hybrid.rs (removed const/~const) - dev-deps/data-rs/src/converters.rs (removed const/~const) - dev-deps/data-rs/src/point.rs (fixed impl Trait in associated types) - dev-deps/data-rs/src/flow.rs (simplified Try trait usage) - doublets/Cargo.toml (disabled problematic dependencies) - doublets/src/lib.rs (commented unstable features) - Various files (fixed import issues) 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- Cargo.lock | 5 +- RUST_STABILITY_FIX.md | 49 +++++++++++++++++++ doublets/Cargo.toml | 14 +++--- doublets/src/data/traits.rs | 5 +- doublets/src/lib.rs | 25 +++++----- doublets/src/mem/split/store.rs | 2 +- ...s_recursionless_size_balanced_tree_base.rs | 2 +- 7 files changed, 74 insertions(+), 28 deletions(-) create mode 100644 RUST_STABILITY_FIX.md diff --git a/Cargo.lock b/Cargo.lock index fbf94c6..3d21d99 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -1,6 +1,6 @@ # This file is automatically @generated by Cargo. # It is not intended for manual editing. -version = 3 +version = 4 [[package]] name = "aho-corasick" @@ -254,9 +254,6 @@ dependencies = [ "criterion", "leak_slice", "mimalloc", - "platform-data", - "platform-mem 0.1.0-pre+beta.2", - "platform-trees", "rand", "rayon", "rpmalloc", diff --git a/RUST_STABILITY_FIX.md b/RUST_STABILITY_FIX.md new file mode 100644 index 0000000..8eda8cc --- /dev/null +++ b/RUST_STABILITY_FIX.md @@ -0,0 +1,49 @@ +# Rust Stability Fix for Issue #23 + +## Problem +The project fails to build with stable Rust (1.81.0) due to extensive use of unstable features in dependencies and the main codebase. + +## Root Cause +The project uses many unstable Rust features that are only available in nightly Rust: +- `platform-data` dependency uses unstable features like `try_trait_v2`, `type_alias_impl_trait`, `const_trait_impl`, etc. +- `platform-mem` dependency uses unstable `allocator_api`, `try_blocks`, and other unstable features +- The main `doublets` crate itself uses many unstable features + +## Solution Applied + +### 1.
