--> tests/ui-stable/try_transmute_mut-size-decrease.rs:20:46

20 | let _decrease_size: Result<&mut u8, _> = try_transmute_mut!(src);

= note: source type: `AU16` (16 bits)
= note: target type: `u8` (8 bits)
= note: this error originates in the macro `$crate::assert_size_eq` which comes from the expansion of the macro `try_transmute_mut` (in Nightly builds, run with -Z macro-backtrace for more info)
