## LayoutError

# Struct LayoutError

1.50.0 · Source

    #[non_exhaustive]pub struct LayoutError;

Expand description

The `LayoutError` is returned when the parameters given to `Layout::from_size_align` or some other `Layout` constructor do not satisfy its documented constraints.

### impl PartialEq for LayoutError

Source§

#### fn eq(&self, other: &LayoutError) -> bool
