Enum MachineIdFileError 

pub enum MachineIdFileError {
    RelativeDataHome {
        data_home: PathBuf,
    },
    Corrupt {
        path: PathBuf,
        reason: String,
    },
    Read {
        path: PathBuf,
        source: Error,
    },
    Write {
        path: PathBuf,
        source: Error,
    },
    Random(Error),
}

Why the daemon could not establish its machine id.

Variants

RelativeDataHome

The data home resolved to a relative path, so the file’s location would depend on the working directory.

Fields

data_home: PathBuf

Corrupt

The file exists but does not hold a machine id. The daemon refuses to start rather than replace it.

Fields

path: PathBuf

reason: String

Read

The file exists but could not be read.

Fields

path: PathBuf

source: Error

Write

A new file could not be written.

Fields

path: PathBuf

source: Error

Random(Error)

The operating system’s random source failed.

Trait Implementations

impl Debug for MachineIdFileError

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

Formats the value using the given formatter.

impl Display for MachineIdFileError

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

Formats the value using the given formatter.

impl Error for MachineIdFileError

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.
