Enum ArraySemantics 

pub enum ArraySemantics {
    Php,
    Reference,
}

How arrays and maps behave when a value is copied.

Examples

use bcgen_lang::ArraySemantics;

assert_eq!(ArraySemantics::default(), ArraySemantics::Php);

Variants

Php

PHP arrays: values. Assigning, passing, returning, capturing, or storing an array copies it (an O(1) copy-on-write dup), a nested write ($a['x']['y'] = 1) separates each intermediate array from any copy that shares it, and writing through null creates the array (auto-vivification).

Reference

Shared references, as in Python, JavaScript, and Ruby: a copy is the same object, nested writes go through, and writing into null is an error.
