pub static LARGE_ASSIGNMENTS: &'static Lint
large_assignments lint detects when objects of large
types are being moved around.
let x = [0; 50000]; let y = x;
warning: moving a large value --> $DIR/move-large.rs:1:3 let y = x; - Copied large value here
When using a large type in a plain assignment or in a function argument, idiomatic code can be inefficient. Ideally appropriate optimizations would resolve this, but such optimizations are only done in a best-effort manner. This lint will trigger on all sites of large moves and thus allow the user to resolve them in code.
