Enum RunError 

#[non_exhaustive]
pub enum RunError {
    NotInteractive,
    Resized {
        cleanup: Option<Error>,
    },
    Io {
        operation: IoOperation,
        source: Error,
        cleanup: Option<Error>,
    },
}

An error that prevents a form from completing normally.

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.

NotInteractive

Standard input and standard error are not both interactive terminals.

Resized

The terminal was resized while an inline prompt configured with crate::InlineResizePolicy::ReturnError was running.

Fields

cleanup: Option<Error>

A terminal restoration failure, if cleanup was attempted and failed.

Io

A runtime operation failed; cleanup is retained separately when it also failed.

Fields

operation: IoOperation

The primary operation that failed.

source: Error

The primary I/O failure.

cleanup: Option<Error>

The first cleanup failure, if cleanup was attempted after source.

Trait Implementations

impl Debug for RunError

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

Formats the value using the given formatter.

impl Display for RunError

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

Formats the value using the given formatter.

impl Error for RunError

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.
