Enum utmp_rs::UtmpError

#[non_exhaustive]
pub enum UtmpError {
    UnknownType(c_short),
    InvalidTime(timeval),

    InvalidUser(Box<[u8]>),

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

UnknownType(c_short)

InvalidTime(timeval)

InvalidLine(Box<[u8]>)

InvalidUser(Box<[u8]>)

InvalidHost(Box<[u8]>)

Trait Implementations

impl Debug for UtmpError

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

Formats the value using the given formatter.

impl Display for UtmpError

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

Formats the value using the given formatter.

impl Error for UtmpError

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

Deprecated since 1.41.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<UtmpError> for ParseError

fn from(source: UtmpError) -> Self

Performs the conversion.
