Enum Error 

#[non_exhaustive]
pub enum Error {
    NoTerminal,
    NotForegroundProcess,
    GetForegroundProcess(Errno),
    ResumeOutput(Errno),
    GetTerminalState(Errno),
    SetTerminalState(Errno),
    TermNotSet,
    InvalidTermName,
    TerminfoNotFound,
    TerminfoUnreadable,
    InvalidTerminfo,

    TerminalWriteMadeNoProgress,
}

An error that stopped ree from resetting the terminal.

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.

NoTerminal

No usable terminal was attached to standard input, output, error, or /dev/tty.

NotForegroundProcess

The process is in a background job and must not change another job’s terminal.

GetForegroundProcess(Errno)

The process could not prove that it owns the terminal foreground.

ResumeOutput(Errno)

The terminal output queue could not be resumed.

GetTerminalState(Errno)

The current terminal driver state could not be read.

SetTerminalState(Errno)

The repaired terminal driver state could not be applied.

TermNotSet

TERM is absent from the process environment.

InvalidTermName

TERM contains characters that cannot name a terminfo entry safely.

TerminfoNotFound

No compiled terminfo entry was found for TERM.

TerminfoUnreadable

A compiled terminfo entry could not be read.

InvalidTerminfo

A compiled terminfo entry was structurally invalid.

TerminalWrite(Errno)

A write to the terminal failed.

TerminalWriteMadeNoProgress

A terminal write returned zero bytes before all reset data was sent.

Implementations

impl Error

pub const fn requires_silent_exit(&self) -> bool

Return whether writing a diagnostic could violate terminal job control.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
