Enum ExecutionControlError 

pub enum ExecutionControlError {
    Transition {
        from: GenerationStatus,
        to: GenerationStatus,
    },
    UnknownEstimate,
    Overflow,
    Limit(&'static str),
}

Portable invalid-state or budget failure, before a native operation is called.

Variants

Transition

The current state does not permit the requested lifecycle edge.

Fields

from: GenerationStatus

Current lifecycle state.

to: GenerationStatus

Requested lifecycle state.

UnknownEstimate

A complete estimate is required before copying or retaining state.

Overflow

Checked arithmetic failed.

Limit(&'static str)

The explicitly admitted logical resource limit was exceeded.

Trait Implementations

impl Clone for ExecutionControlError

fn clone(&self) -> ExecutionControlError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExecutionControlError

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

Formats the value using the given formatter.

impl Display for ExecutionControlError

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

Formats the value using the given formatter.

impl Eq for ExecutionControlError

impl Error for ExecutionControlError

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 ExecutionControlError

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

Equality operator ==.

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

Inequality operator !=.
