Struct Package 

pub struct Package {
    pub name: String,
    pub exports: BTreeMap<String, WeftHash>,
    pub defs: BTreeMap<WeftHash, Def>,
}

A distributable set of definitions plus the petnames it exports.

Fields

name: String

Human-facing package name (informational — identity lives in hashes).

exports: BTreeMap<String, WeftHash>

Petname → definition hash. What use-ing this package gives you.

defs: BTreeMap<WeftHash, Def>

Every definition the exports (transitively) need, keyed by hash.

Implementations

impl Package

pub fn build( name: &str, defs: Vec<Def>, exports: Vec<(&str, usize)>, ) -> Result<Self, WeftError>

Build a package from defs + (petname, def_index) export pairs.

pub fn verify(&self) -> Result<(), WeftError>

A package must be self-verifying: every def’s hash matches its bytes, every export points at a def, and the whole set verifies as a module (types, effects, fuel — the full trust boundary, locally).

pub fn export(&self, petname: &str) -> Option<WeftHash>

The export’s hash, by petname.
