Struct PackageSpec 

pub struct PackageSpec {
    pub arg_index: usize,
    pub name: String,
    pub version: Option<String>,
}

A package spec found in an interpreter entry’s args.

Fields

arg_index: usize

Index into args where the spec sits, so a caller can rewrite it.

name: String

Package name, including any @scope/ prefix.

version: Option<String>

Version suffix, if the spec carries one. None means the spec floats: the package manager resolves it fresh on every start.

Implementations

impl PackageSpec

pub fn floats(&self) -> bool

true when no version is recorded — the resolved code can change between two starts with no user action and no signal.

pub fn to_arg(&self) -> String

The spec as it appears (and would be written) in args.
