wasm-manifest

Manifest and lockfile format types for WebAssembly packages.

This crate provides types for parsing and serializing WASM package manifests (wasm.toml) and lockfiles (wasm.lock).

Manifest Format

The manifest file (deps/wasm.toml) supports two dependency formats:

Compact format

[dependencies]
"wasi:logging" = "ghcr.io/webassembly/wasi-logging:1.0.0"
"wasi:key-value" = "ghcr.io/webassembly/wasi-key-value:2.0.0"

Explicit format

[dependencies."wasi:logging"]
registry = "ghcr.io"
namespace = "webassembly"
package = "wasi-logging"
version = "1.0.0"

Lockfile Format

The lockfile (deps/wasm.lock) tracks resolved dependencies:

version = 1

[[package]]
name = "wasi:logging"
version = "1.0.0"
registry = "ghcr.io/webassembly/wasi-logging"
digest = "sha256:a1b2c3d4..."

[[package.dependencies]]
name = "wasi:logging"
version = "1.0.0"
