Enum InstallError 

pub enum InstallError {
    AlreadyInstalled {
        name: String,
    },
    AlreadyInstalling {
        name: String,
    },
    CurrentlyUpdating {

    NoInstallers,
    NoCompatibleInstaller {

    },
    NoScopeCompatibleInstaller {
        host: HostProfile,

    CommandAlreadyExposed {
        command: String,
        package: String,

    CommandClaimedWhileInProgress {
        command: String,
    },
    RuntimeBootstrapDeclined {
        runtime: String,
    },
    Cancelled,
    Unexpected(Error),
}

User-facing error type produced by the install pipeline.

The variants intentionally map to coarse categories rather than exposing the raw implementation details from catalog resolution, checksum verification, cancellation, and rollback. This keeps the CLI behavior predictable while still preserving enough context for diagnostics and testing.

Implementations

impl InstallError

pub fn failure_class(&self) -> InstallFailureClass

Group the error into a coarse failure class for reporting and rollback.

Trait Implementations

impl Debug for InstallError

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

Formats the value using the given formatter.

impl Display for InstallError

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

Formats the value using the given formatter.

impl Error for InstallError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting
