Enum GiveUp 

pub enum GiveUp {
    Stopped,
    Refused {
        limit: OperationError,
        refused_bytes: Option<u64>,
    },
    OutOfMemory,
    Invalid(String),
}

Why a compile has no diagram to return.

Variants

Stopped

The compile stopped short at its deadline. A caller with a fallback runs it; nothing partial is ever returned, so a count taken from a compile that did not give up is exact. The library’s OperationError::Stopped is the same stop, one level down.

Refused

The compile stopped short because an apply was refused under the batch limits: limit is OverBudget (memory) or OutputCap (size), and refused_bytes the request the allocator refused, when it was one. A caller treats it as GiveUp::Stopped.

Fields

limit: OperationError

The limit the apply reached.

refused_bytes: Option<u64>

The size of the refused allocation, if the allocator refused one.

OutOfMemory

An allocation was refused while reducing the finished diagram. The binary reports it with the diagnostic crate::Error carries, which is what a benchmark harness reads to classify the run as out of memory.

Invalid(String)

The caller’s input does not fit together: the vtree does not place exactly the formula’s variables, a ComponentPlan::Split does not partition the formula, or the output’s variables or weights do not cover the requested formula. The text says which.

Trait Implementations

impl Clone for GiveUp

fn clone(&self) -> GiveUp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GiveUp

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

Formats the value using the given formatter.

impl Display for GiveUp

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

Formats the value using the given formatter.

impl Error for GiveUp

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<GiveUp> for Error

A give-up as the run reports it: a stop or a refusal ends the run without a count, and inputs that do not fit fail the compile stage.

fn from(give_up: GiveUp) -> Self

Converts to this type from the input type.

impl PartialEq for GiveUp

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