Enum ExternalProgramError 

pub enum ExternalProgramError {
    Command(String),
    ForegroundOwnershipUnconfirmed {
        message: String,
        diagnostic: ForegroundRestorationDiagnostic,
    },
}

Failure while an interactive external program temporarily owns the terminal.

Variants

Command(String)

ForegroundOwnershipUnconfirmed

Fatal failure because Tau could not confirm foreground ownership.

Fields

pub fn is_foreground_ownership_unconfirmed(&self) -> bool

Returns whether the interactive attachment must exit without resuming.

pub fn foreground_restoration_diagnostic( &self, ) -> Option<ForegroundRestorationDiagnostic>

Returns the bounded restoration diagnostic for an ownership fail-stop.

Trait Implementations

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<String> for ExternalProgramError

fn from(error: String) -> Self

Converts to this type from the input type.
