Enum OutOfMemory

pub enum OutOfMemory {
    TryReserve(TryReserveError),
    ExternalApi,
}

Error returned when an operation ran out of memory

The library is not fully memory safe, meaning there are cases where memory allocation failing can lead to a panic instead to an error. Mainly add clauses to solvers and collecting clauses from encodings are done in a safe way. This is intended, e.g., for anytime solvers that might want a change to print a final output if they run out of memory.

Variants

TryReserve(TryReserveError)

A try_reserve operation in Rust ran out of memory

ExternalApi

An external API (typically a solver) ran out of memory

Trait Implementations

impl Debug for OutOfMemory

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

Formats the value using the given formatter.

impl Display for OutOfMemory

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

Formats the value using the given formatter.

impl Error for OutOfMemory

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<OutOfMemory> for ConstraintEncodingError

fn from(source: OutOfMemory) -> Self

Converts to this type from the input type.

fn from(source: OutOfMemory) -> Self

Converts to this type from the input type.

impl From<OutOfMemory> for EncodingError

Available on crate feature proof-logging only.

fn from(source: OutOfMemory) -> Self

Converts to this type from the input type.

impl From<TryReserveError> for OutOfMemory

fn from(value: TryReserveError) -> Self

Converts to this type from the input type.

impl PartialEq for OutOfMemory

fn eq(&self, other: &OutOfMemory) -> 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.
