# rust-toolchain.toml
#
# This repository uses a pinned Rust toolchain for reproducible builds across:
# - core engine (Rust)
# - services (Rust)
# - SDK (Rust)
# - CI pipelines (GitHub Actions)
#
# IMPORTANT:
# - Solana/Anchor program builds typically rely on the Solana toolchain distributed by Solana/Anchor
#   (including a specific rustc + LLVM toolchain for BPF/SBF). This file pins the *host* toolchain used
#   for off-chain components and tooling (clippy/rustfmt/cargo).
# - If you build Anchor programs, install Solana + Anchor as documented by those projects. Your program
#   builds will still work because Anchor uses the Solana toolchain for SBF compilation.
#
# To check the active toolchain:
#   rustc --version
#   cargo --version
#
# To install exactly what this file requests:
#   rustup show
#   rustup toolchain install 1.78.0 --profile minimal --component rustfmt --component clippy
#
# For contributors:
# - Keep this file in sync with CI (see .github/workflows/*).
# - Prefer stable pins for production and only use nightly for dedicated fuzzing/profiling tasks.
#
# =============================================================================

[toolchain]
# Pin to a specific stable release for deterministic compilation.
# If you bump this, bump CI caches and verify all crates compile (engine + services + sdk).
channel = "1.78.0"

# The minimal profile avoids downloading docs and extra components by default.
# You can switch to "default" if you want docs/std sources installed automatically.
profile = "minimal"

# Common components used by developers and CI.
# - rustfmt: formatting
# - clippy: linting
# - rust-src: required by some IDEs and by certain cross-compilation workflows
# - llvm-tools-preview: enables coverage/profiling tools (llvm-cov, etc.)
components = [
  "rustfmt",
  "clippy",
  "rust-src",
  "llvm-tools-preview"
]

# Cross compilation targets used across the repo:
# - x86_64-unknown-linux-gnu: CI + common servers
# - aarch64-unknown-linux-gnu: ARM servers (Graviton, etc.)
# - x86_64-apple-darwin / aarch64-apple-darwin: macOS developer machines
# - wasm32-unknown-unknown: optional (dashboard tooling / future wasm clients)
#
# NOTE: Solana SBF target is handled by Solana toolchain, not rustup targets.
targets = [
  "x86_64-unknown-linux-gnu",
  "aarch64-unknown-linux-gnu",
  "x86_64-apple-darwin",
  "aarch64-apple-darwin",
  "wasm32-unknown-unknown"
]

# =============================================================================
# Optional: Per-directory overrides
#
# If you want nightly for fuzzing, do NOT change the global pin above.
# Instead, place a rust-toolchain.toml inside the fuzz directory.
#
# Example (already scaffolded in tests/fuzz/programs/rust-toolchain.toml):
#
#   [toolchain]
#   channel = "nightly"
#   components = ["llvm-tools-preview"]
