Enum Error 

#[non_exhaustive]
pub enum Error {
    NoControllingTty,
    EditorNotFound(String),
    EditorNonZeroExit(i32),
    InvalidEditorCommand(String),
    TempFileDeleted(PathBuf),
    InvalidBuilderConfiguration(&'static str),
    CompatibilityViolation(&'static str),
    Io(Error),
}

Errors returned by the rusty_vipe library API.

Marked #[non_exhaustive] so future variant additions are not breaking changes within a major version.

Examples

use rusty_vipe::Error;

// Errors implement Display via thiserror.
let e = Error::EditorNonZeroExit(42);
assert_eq!(e.to_string(), "editor exited with code 42");

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.

NoControllingTty

Opening the controlling terminal failed (/dev/tty on Unix or CONIN$/CONOUT$ on Windows). Typical cause: process is running without a controlling terminal (CI, cron, nohup-detached, headless Docker RUN step).

EditorNotFound(String)

No editor could be resolved from the precedence ladder, OR the editor binary was not found at spawn time. Carries the editor command or env-var value that was attempted.

EditorNonZeroExit(i32)

The editor exited with a non-zero code. Per FR-006, this carries the already-clamped exit code (Unix 1–255 verbatim; Windows 1–254 verbatim, else clamped to 1). Library consumers can pattern-match on a known range.

InvalidEditorCommand(String)

shell-words parsing of an editor env value ($VISUAL/$EDITOR) or --editor=<cmd> flag failed. Carries the original input.

TempFileDeleted(PathBuf)

The tempfile no longer exists after the editor returned. Typical cause: user deleted it from within the editor (e.g., :!rm <file>).

InvalidBuilderConfiguration(&'static str)

The builder was configured into an impossible state.

CompatibilityViolation(&'static str)

A Default-mode-only setting was passed to Strict mode (or vice versa).

Io(Error)

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.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
