Expand description

Abstraction over a system package manager.

Required Methods§

Source

fn name(&self) -> &'static str

Stable lowercase identifier (e.g. "pacman", "apt").

This matches the field name in DepsGroup in the config schema.

Source

fn is_available(&self) -> bool

Returns true when the manager’s binary is on PATH.

Source

fn exists(&self, runner: &dyn Runner, pkg: &str) -> Result<bool, PackageError>

Returns true when pkg can be installed from the manager’s configured sources (repositories, taps, buckets, registry), whether or not it is installed. Used by krypt deps --check.

Source

fn is_installed( &self, runner: &dyn Runner, pkg: &str, ) -> Result<bool, PackageError>

Returns true when pkg is already installed.

Only errors on unexpected conditions — a clean “not installed” (exit 1 from a query command) is returned as Ok(false).

Source

fn install( &self, runner: &dyn Runner, packages: &[String], ) -> Result<(), PackageError>

Install the given packages.

Implementations may batch packages into a single invocation or loop one at a time (winget).

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
