Enum SolveError 

#[non_exhaustive]
pub enum SolveError {
    ThreadOverflow,
    ThreadSpawnError,
}

Errors that result from problems solving

Most of of these are either caused by invalid arguments or problems creating threads when using multi-threaded solving. If explicitely using single threaded, or the input parameters are validated in advance, these can be safely unwrapped.

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.

ThreadOverflow

Returned when the requested number of threads was too large

ThreadSpawnError

Returned when a multi-threaded solver couldn’t create a thread pool

Trait Implementations

impl Clone for SolveError

fn clone(&self) -> SolveError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SolveError

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

Formats the value using the given formatter.

impl Display for SolveError

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

Formats the value using the given formatter.

impl Error for SolveError

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<ThreadPoolBuildError> for SolveError

fn from(_: ThreadPoolBuildError) -> Self

Converts to this type from the input type.

impl PartialEq for SolveError

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