Mojo struct

Origin

@register_passable(trivial) struct Origin[is_mutable: Bool]

This represents a origin reference for a memory value.

Parameters

cast_from = _lit_mut_cast[is_mutable, ?]: Cast an existing Origin to be of the specified mutability. This is a low-level way to coerce Origin mutability. This should be used rarely, typically when building low-level fundamental abstractions. Strongly consider alternatives before reaching for this "escape hatch".

Safety: This is an UNSAFE operation if used to cast an immutable origin to a mutable origin.

Examples:

Cast a mutable origin to be immutable:
```
struct Container[mut: Bool, //, origin: Origin[mut]]:
    var data: Int

    fn imm_borrow(self) -> Container[ImmutableOrigin.cast_from[origin].result]:
        # ...
```
```
struct Container[mut: Bool, //, origin: Origin[mut]]:
    var data: Int

    fn imm_borrow(self) -> Container[ImmutableOrigin.cast_from[origin].result]:
        # ...
```
empty = {}: An empty __origin_of() of the given mutability. The empty origin is guaranteed not to alias any existing origins.
