Enum UdevInstallError 

pub enum UdevInstallError {
    Io {
        action: &'static str,
        path: PathBuf,
        source: Error,
    },

        args: Vec<String>,
        code: Option<i32>,
    },
    MissingUser,
}

A filesystem, environment, or system-command failure during rule installation.

Variants

Io

Writing a rule file or setting its permissions failed.

Fields

action: &'static str

The filesystem operation that failed.

path: PathBuf

The rule-file path.

source: Error

The underlying filesystem error.

CommandSpawn

A required system command could not be started.

Fields

program: String

The program that could not be started.

source: Error

The underlying process-spawn error.

CommandFailed

A system command returned an unsuccessful status.

Fields

program: String

The program that failed.

args: Vec<String>

The arguments passed to the program.

code: Option<i32>

The exit code, or None if the process ended without one.

MissingUser

No nonempty user name was found in SUDO_USER, USER, or LOGNAME.

Implementations

impl UdevInstallError

pub fn needs_root(&self) -> bool

Returns whether elevated privileges may resolve this error.

This is a hint: permission-denied I/O errors and all unsuccessful command statuses return true, even if privileges were not the cause.

Trait Implementations

impl Debug for UdevInstallError

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

Formats the value using the given formatter.

impl Display for UdevInstallError

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

Formats the value using the given formatter.

impl Error for UdevInstallError

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>)
