Enum KexecError 

pub enum KexecError {
    SignatureRejected,
    LockdownRefused,
    UnsupportedImage,
    Io(Error),
    InvalidPath(PathBuf),
    Unsupported,
}

Errors returned while preparing or invoking kexec.

Classification is deliberately narrow so the TUI can render a specific, user-actionable diagnostic instead of a black screen.

Variants

SignatureRejected

Kernel signature verification (KEXEC_SIG) rejected the image.

Maps to EKEYREJECTED from kexec_file_load(2). Typical cause: the ISO’s kernel is self-signed or signed by a CA not present in the platform / MOK keyring. User remedy: enroll the key via mokutil.

LockdownRefused

Kernel lockdown / Secure Boot refused the operation.

Maps to EPERM from kexec_file_load(2) when lockdown is integrity or confidentiality mode. User remedy: none — by design.

UnsupportedImage

Image format rejected by the kernel’s file loader (e.g. not a bzImage).

Maps to ENOEXEC.

Io(Error)

Underlying I/O or file-descriptor failure.

InvalidPath(PathBuf)

Caller supplied a path containing an interior NUL byte.

Unsupported

Crate compiled for a non-Linux target; no kexec available.

Trait Implementations

impl Debug for KexecError

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

Formats the value using the given formatter.

impl Display for KexecError

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

Formats the value using the given formatter.

impl Error for KexecError

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for KexecError

fn from(source: Error) -> Self

Converts to this type from the input type.
