Enum PtySessionError 

#[non_exhaustive]
pub enum PtySessionError {
    PtyCreation(String),
    SpawnFailed(String),
    WriteFailed(String),
    Timeout(String),
    Assertion(Box<AssertionFailure>),
}

Errors that can occur during PTY session operations.

Marked #[non_exhaustive] so future variants such as PtySessionError::Assertion stay non-breaking. Downstream match arms must include a fallback _ arm.

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.

PtyCreation(String)

Failed to create the PTY.

SpawnFailed(String)

Failed to spawn the child process.

WriteFailed(String)

Failed to write to the PTY.

Timeout(String)

A wait operation timed out.

Assertion(Box<AssertionFailure>)

A Step::Eventually predicate never returned Ok(()) before its timeout elapsed. Carries the last AssertionFailure the predicate produced so the proof report can render the structured failure context.

Trait Implementations

impl Debug for PtySessionError

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

Formats the value using the given formatter.

impl Display for PtySessionError

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

Formats the value using the given formatter.

impl Error for PtySessionError

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.
