Enum AssertionError

pub enum AssertionError {
    TraceWidthTooShort(usize, usize),
    TraceLengthNotPowerOfTwo(usize),
    TraceLengthTooShort(usize, usize),
    TraceLengthNotExact(usize, usize),
}

Represents an error returned during assertion evaluation.

Variants

TraceWidthTooShort(usize, usize)

This error occurs when an assertion is evaluated against an execution trace which does not contain a column specified by the assertion.

TraceLengthNotPowerOfTwo(usize)

This error occurs when an assertion is evaluated against an execution trace with length which is not a power of two.

TraceLengthTooShort(usize, usize)

This error occurs when an assertion is evaluated against an execution trace which does not contain a step against which the assertion is placed.

TraceLengthNotExact(usize, usize)

This error occurs when a Sequence assertion is placed against an execution trace with length which conflicts with the trace length implied by the assertion.

Trait Implementations

impl Debug for AssertionError

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

Formats the value using the given formatter.

impl Display for AssertionError

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

Formats the value using the given formatter.

impl Error for AssertionError

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 PartialEq for AssertionError

fn eq(&self, other: &AssertionError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
