Enum ControlFlow 

pub enum ControlFlow {
    Break,
    Continue,
    Return(Value),
    Err(Error),
}

An enum carrying control flow information.

Returned by compute functions which can impact control flow.

Variants

Break

Continue

Return(Value)

Err(Error)

Implementations

impl ControlFlow

pub fn is_ignorable(&self) -> bool

Returns true if this represents a data-shape error that can safely be treated as Value::None (e.g., type mismatches, coercion failures).

Returns false for system errors (storage, timeout, permissions), control flow signals (Break/Continue), and Return values.

Trait Implementations

impl Debug for ControlFlow

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

Formats the value using the given formatter.

impl Display for ControlFlow

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

Formats the value using the given formatter.

impl From<Error> for ControlFlow

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<Error> for ControlFlow

fn from(error: Error) -> Self

Boxes the value-algebra failure directly, so it stays the concrete type in the anyhow slot and ControlFlow::is_ignorable keeps matching it.
