Struct ExternalPackages 

pub struct ExternalPackages { /* private fields */ }

Packages to reference rather than generate, keyed by package id or package name.

The name form is the one to prefer: a package id is the hash of one build, so pinning by id stops matching the moment the dependency is rebuilt, while the name survives a version bump — which is the whole point of addressing packages by name under Smart Contract Upgrade.

Implementations

impl ExternalPackages

pub fn new() -> Self

An empty map — everything in the DAR is generated.

pub fn with(self, key: impl Into<String>, crate_name: impl Into<String>) -> Self

Reference the package identified by key (its name, or its id hash) at the crate crate_name, instead of generating it.

pub fn crate_names(&self) -> Vec<String>

The crate names named here, sorted — what a generated manifest must depend on.
