Enum naga::back::spv::block::ExpressionPointer

enum ExpressionPointer {
    Ready {
        pointer_id: Word,
    },
    Conditional {
        condition: Word,
        access: Instruction,
    },
}

The results of emitting code for a left-hand-side expression.

On success, write_expression_pointer returns one of these.

Variants

Ready

The pointer to the expression’s value is available, as the value of the expression with the given id.

Fields

pointer_id: Word

Conditional

The access expression must be conditional on the value of condition, a boolean expression that is true if all indices are in bounds. If condition is true, then access is an OpAccessChain instruction that will compute a pointer to the expression’s value. If condition is false, then executing access would be undefined behavior.

Fields

condition: Word

access: Instruction
