Enum Manager 

pub enum Manager {
    Uv,
    Pip,
    Cargo,
    Npm,
    Brew,
    Dotnet,
}

A supported package manager. The set is closed on purpose: the engine only runs managers whose install/uninstall argv it fully controls.

Variants

Uv

Astral uv — uv tool install <pkg>==<ver> (Python CLIs).

Pip

pip — pip install --user <pkg>==<ver> (Python libraries/CLIs).

Cargo

cargo — cargo install <pkg> --version <ver> (Rust binaries).

Npm

npm — npm install -g <pkg>@<ver> (Node CLIs).

Brew

Homebrew — brew install <formula> (version pinned via the formula name, e.g. node@22; the version field documents the expected version).

Dotnet

.NET SDK — dotnet tool install --global <pkg> --version <ver> (.NET global tools published to NuGet, e.g. CodeCompress.Server).

Implementations

impl Manager

pub fn parse(s: &str) -> Option<Self>

Parse a manager slug from a manifest, case-insensitively. Unknown → None.

pub fn as_str(self) -> &'static str

Canonical slug (also the default executable name).

pub fn program(self) -> String

The executable to invoke — the LEANCTX_BOOTSTRAP_<MANAGER> override if set + non-empty, otherwise the manager’s name (resolved via PATH).

pub fn install_hint(self) -> &'static str

A short, actionable hint for installing this manager when it is absent — surfaced by the addon add pre-flight so a missing manager fails with a “here’s how to get it” message rather than a raw spawn error.

pub fn is_available(self) -> bool

Whether the manager’s executable can actually be launched: its LEANCTX_BOOTSTRAP_<MANAGER> override path is executable, or its bare name resolves on PATH. Lets addon add pre-flight a missing manager.

Trait Implementations

impl Clone for Manager

fn clone(&self) -> Manager

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Manager

impl Debug for Manager

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Manager

impl PartialEq for Manager

fn eq(&self, other: &Manager) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
