fast-di-compile:download-binary

Downloads a verified platform binary for fast-di-compile, the Rust DI compiler by Anton Siniorg (speedupmate).

n98-magerun2 fast-di-compile:download-binary

The command detects Linux or macOS and x64 or arm64 automatically. It downloads the matching release archive from speedupmate/di-compiler and installs the executable at:

bin/fast-di-compile

Use --release for a specific release, --platform to override platform detection, and --force to replace a binary that does not match the selected release. --version is reserved by Symfony Console for n98-magerun2 itself.

n98-magerun2 fast-di-compile:download-binary --release=v1.0.3 --platform=linux-arm64

Verification

The command obtains SHA-256 asset digests from the GitHub release API. It verifies the downloaded checksum file and archive before extracting the executable. A binary already present at the target location is preserved unless it matches the selected release or --force is passed.

How Rust Is Used

The downloaded program is a Rust implementation of Magento's DI compilation. The companion spmt/magento2-spmt-fast-di-compile module replaces Magento's setup:di:compile command with a wrapper when this executable is available. The wrapper passes the Magento root to the Rust binary, which generates DI code and metadata; Magento falls back to its standard PHP compiler if the binary is unavailable or --standard is selected.

This command only downloads the compiler binary. A separate fast-di-compile:install command will install and enable the companion Magento module in a later release.
