This is an enumeration used in Stencila Schema describing whether and why execution is required.

It exists to distinguish different re-execution states, such as stale dependencies or changed content, in a way that user interfaces and automation can interpret consistently.

See Executable.executionRequired for the property that uses this enumeration.

Members

The ExecutionRequired type has these members:

Member	Description
`No`	No re-execution is required, the semantics of the node and its dependencies has not changed since it was last executed
`NeverExecuted`	Execution is required because the node has never been executed (or any previous execution was not persisted in its state).
`StateChanged`	Re-execution is required because the state of the node (e.g. source code) has changed since it was last executed and no semantic digest is available to determine if semantics changed.
`SemanticsChanged`	Re-execution is required because the semantics of the node has changed since it was last executed.
`DependenciesChanged`	Re-execution is required because the semantics of one or more dependencies (including transitive dependencies) changed since it was last executed.
`DependenciesFailed`	Re-execution is required because one or more dependencies (including transitive dependencies) failed when it was last executed.
`ExecutionFailed`	Re-execution is required because execution failed (there were errors or exceptions) the last time it was executed.
`ExecutionCancelled`	Re-execution may be required because execution was pending but was cancelled.
`ExecutionInterrupted`	Re-execution is required because execution was interrupted the last time it was executed.
`KernelRestarted`	Re-execution is required because the kernel that the node was last executed in was restarted.
`UserRequested`	Execution is required because it was explicitly requested by a user.
