        unit: usize,
    },

Failure to construct or execute a logical stack shuffle.

Variants

ZeroWidthGroup

A logical value group has no units.

Fields

group: usize

Index of the invalid group, counted from the bottom of the stack.

UnknownUnit

An output unit does not name a unit in the input layout.

Fields

unit: usize

Invalid logical input-unit index.

SplitGroup

An output layout selects only part of a value group or changes its unit order.

Fields

group: usize

Index of the offending group, counted from the bottom of the stack.

LayoutMismatch

The live stack does not have the layout for which the plan was validated.

Fields

group: usize

First expected group that was absent or had a different width.

expected: usize

Width recorded in the plan, or zero when the plan has no such group.

actual: usize

Width found on the stack, or zero when the stack has no such group.

Stack(StackError)

The staged output cannot be represented by the operand stack.
