#totto2727/x/copy
Defines explicit logical-copy behavior for built-in MoonBit values and downstream types that need an independent mutable result. See the module README for consumer setup and package imports.
#Usage
Copy a mutable collection before changing it so the original value remains available for comparison or reuse.
///|
test {
let source = [1, 2]
let copied = Copy::copy(source)
copied[0] = 3
debug_inspect((source, copied), content="([1, 2], [3, 2])")
}#Package behavior
- Built-in implementations for scalars, collections, options, results, maps, and tuples
- Recursive copying for composite values
- An open trait for downstream value types to define their own semantics
#API

Copy
pub(open) trait Copy {
fn copy(Self) -> Self
}Describes values that can produce an independent logical copy.
Implementations for composite values recursively copy their contents. An
implementation may share immutable internal storage when doing so cannot
expose mutation through the returned value.
This trait is open so downstream value types can define their own copy
semantics.
