At a glance

Fix Fastly Compute Rust build failures caused by edition2024 dependencies.

  • Cargo build fails with feature edition2024 is required
  • SKILL.md covers Problem, Context / Trigger Conditions, Solution and Verification, plus 3 more sections
  • Calls cargo
  • Wasip2 crates fail to download/parse

What it does

Fastly Compute Rust Edition2024 Fix is an agent skill from divinevideo/divine-mobile. Fix Fastly Compute Rust build failures caused by edition2024 dependencies. Use when: (1) cargo build fails with "feature edition2024 is required", (2) wit-bindgen or wasip2 crates fail to download/parse, (3) Fastly SDK pulls in incompatible transitive dependencies, (4) Build worked before but fails after dependency update. Solves by pinning wit-bindgen, wasip2, and related crates to pre-edition2024 versions.

Its SKILL.md is about 690 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Dependency management. It works with Rust and WebAssembly. The licence is MPL-2.0.

When your agent uses it

  • Cargo build fails with feature edition2024 is required
  • Wasip2 crates fail to download/parse
  • Fastly SDK pulls in incompatible transitive dependencies
  • Build worked before but fails after dependency update

Example prompts

  • “feature edition2024 is required”
  • “/fastly-compute-rust-edition2024-fix”

What it can do on your machine

Read from SKILL.md and the folder at commit c3d6f7e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • cargo

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • docs.fastly.com
    • doc.rust-lang.org

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Fastly Compute Rust Edition2024 Fix loads about 687 tokens when it runs. Until then it costs about 112 tokens; SKILL.md has 175 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~112
When it runs · the whole SKILL.md, loaded when a task matches
~687

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Fastly Compute Rust Edition2024 Dependency Fix

Problem

Fastly Compute Rust projects fail to build with errors about edition2024 being required, even when using stable Rust. The error appears when transitive dependencies (especially wit-bindgen 0.51+ and wasip2 1.0.2+) require Rust 1.87+ which isn't stable yet.

Context / Trigger Conditions

  • Error: feature 'edition2024' is required
  • Error: failed to parse manifest at .../wit-bindgen-0.51.0/Cargo.toml
  • Error mentions "requires Rust 1.87.0" for wit-bindgen or wasip2
  • Build previously worked but fails after running cargo update
  • Using Fastly SDK (fastly crate) version 0.11.x

Solution

Pin the problematic transitive dependencies in your Cargo.toml:

toml
[dependencies]
# Fastly Compute SDK - pin to specific version
fastly = "=0.11.12"

# Pin these to avoid edition2024 requirement
wit-bindgen = "=0.46.0"
wasip2 = "=1.0.1"

# Also pin these if you use k256 or crypto
k256 = { version = "=0.13.3", features = ["schnorr"] }
base64ct = "=1.6.0"

Also update rust-toolchain.toml to include both WASM targets:

toml
[toolchain]
channel = "1.83.0"
targets = ["wasm32-wasi", "wasm32-wasip1"]

Then:

bash
rm Cargo.lock
rustup target add wasm32-wasip1
cargo build --target wasm32-wasi

Verification

Build should complete without edition2024 errors:

bash
cargo build --target wasm32-wasi 2>&1 | grep -i "edition2024"
# Should return nothing (no matches)

Example

Before fix (Cargo.toml):

toml
[dependencies]
fastly = "0.11"  # Allows 0.11.x which pulls wit-bindgen 0.51+

After fix (Cargo.toml):

toml
[dependencies]
fastly = "=0.11.12"
wit-bindgen = "=0.46.0"
wasip2 = "=1.0.1"

Notes

  • The = prefix in version strings means "exactly this version"
  • Fastly CLI 13.x switched from wasm32-wasi to wasm32-wasip1 target
  • This is a temporary fix until Rust 1.87 becomes stable
  • The warning about wasm32-wasi being renamed to wasm32-wasip1 is expected
  • When Rust 1.87 is stable, these pins can be removed
