Enum ExecutionControlFlow 

pub enum ExecutionControlFlow {
    Normal,
    BreakLoop {
        levels: usize,
    },
    ContinueLoop {
        levels: usize,
    },
    ReturnFromFunctionOrScript,
    ExitShell,
}

Represents a control flow transition to apply.

Variants

Normal

Continue normal execution.

BreakLoop

Break out of an enclosing loop.

Fields

levels: usize

Identifies which level of nested loops to break out of. 0 indicates the innermost loop, 1 indicates the next outer loop, and so on.

ContinueLoop

Continue to the next iteration of an enclosing loop.

Fields

levels: usize

Identifies which level of nested loops to continue. 0 indicates the innermost loop, 1 indicates the next outer loop, and so on.

ReturnFromFunctionOrScript

Return from the current function or script.

ExitShell

Exit the shell.

Implementations

impl ExecutionControlFlow

pub const fn try_decrement_loop_levels(&self) -> Self

Attempts to decrement the loop levels for BreakLoop or ContinueLoop. If the levels reach zero, transitions to Normal. If the control flow is not a loop break or continue, no changes are made.

Trait Implementations

impl Clone for ExecutionControlFlow

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ExecutionControlFlow

impl Default for ExecutionControlFlow

fn default() -> Self

Returns the “default value” for a type.
