}

Implementations

impl Installer

pub(crate) fn from_env(exe_dir: Option<&Path>) -> Result<Self, InstallerError>

pub(crate) fn install( &self, extension: &str, source: &InstallSource, dry_run: bool, quiet: bool, ) -> Result<InstallResult, InstallerError>

Installs an extension and returns the installed version and description.

pub(crate) fn check_latest_version( source: &InstallSource, installed_version: Option<&str>, ) -> Result<Option<String>, InstallerError>

Checks if a newer version is available without installing. Returns Some(latest_version) if the manifest version is strictly newer, None if already up to date.

pub(crate) fn install_if_changed( &self, extension: &str, source: &InstallSource, installed_version: Option<&str>, ) -> Result<Option<InstallResult>, InstallerError>

Installs an extension only if the manifest version is newer than installed_version. Returns Some(result) if an update was performed, None if already at the latest version.

fn install_inner( &self, extension: &str, source: &InstallSource, manifest: Option<ReleaseManifest>, dry_run: bool, quiet: bool, ) -> Result<InstallResult, InstallerError>

Shared implementation for install and install_if_changed.

pub(crate) fn remove( &self, extension: &str, dry_run: bool, ) -> Result<(), InstallerError>

Removes an extension’s binary and skill files.

fn resolve_install( &self, extension: &str, source: &InstallSource, pre_manifest: Option<ReleaseManifest>, dry_run: bool, quiet: bool, ) -> Result<ResolvedInstall, InstallerError>

Fetches the manifest, downloads the binary, and verifies checksums/signatures.

fn copy_binary( &self, resolved: &ResolvedInstall, dry_run: bool, quiet: bool, ) -> Result<(), InstallerError>

Atomically places the downloaded binary at its destination path.

fn remove_binary( &self, binary: &str, dry_run: bool, ) -> Result<(), InstallerError>

Deletes the named binary from bin_dir.

fn ensure_dirs(&self, dry_run: bool) -> Result<(), InstallerError>

Creates bin_dir if it doesn’t exist and verifies it is writable.

Trait Implementations
