Struct PkgInfo 

pub struct PkgInfo {
    pub name: Option<String>,
    pub version: Option<Version>,
    pub strict: bool,
    pub deps: HashMap<String, DepEntry>,
}

The object responsible for locating and selecting dependency modules for each MettaMod

This structure is conceptually analogous to the a Cargo.toml file for a given module.

Fields

name: Option<String>

The public name of the module

Should be composed of alpha-numeric characters with ‘-’ and ‘_’ characters allowed. Must not contain any other punctuation

version: Option<Version>

The version of this module

A None or missing version is considered inferior to all other versions

strict: bool

If strict == true then a dependency must be declared in the PkgInfo, otherwise a permissive version requirement will be assumed for any modules that are not explicitly declared

deps: HashMap<String, DepEntry>

Requirements for each dependency sub-module

A Duplicate entry for a given sub-module in the deps list is an error.
