AllocationError

pub enum AllocationError

Classifies recoverable raw-storage and layout failures.

The cases are portable and allocation-free. They intentionally preserve no target allocator status code; target-private adapters translate at their boundary.

Example

module example.allocation_error;
from std.memory import AllocationError, Layout;
fn Main() -> i32 {
    switch Layout.ArrayOf<u64>(4) {
        case .Ok { Value = _ } => return 0;
        case .Err { Error = Error } => {
            if Error == .SizeOverflow { return 2; }
            return 1;
        }
    }
}
