Matthias Krüger 53afa97eb7 Rollup merge of #136083 - bend-n:⃤⃤, r=lcnr ... Suggest {to,from}_ne_bytes for transmutations between arrays and integers, etc implements #136067 Rust has helper methods for many kinds of safe transmutes, for example integer<->bytes. This is a lint against using transmute for these cases. ```rs fn bytes_at_home(x: [u8; 4]) -> u32 { transmute(x) } // other examples transmute::<[u8; 2], u16>(); transmute::<[u8; 8], f64>(); transmute::<u32, [u8; 4]>(); transmute::<char, u32>(); transmute::<u32, char>(); ``` It would be handy to suggest `u32::from_ne_bytes(x)`. This is implemented for `[u8; _]` -> `{float int}` This also implements the cases: `fXX` <-> `uXX` = `{from_bits, to_bits}` `uXX` -> `iXX` via `cast_unsigned` and `cast_signed` {`char` -> `u32`, `bool` -> `n8`} via `from` `u32` -> `char` via `from_u32_unchecked` (note: notes `from_u32().unwrap()`) (contested) `u8` -> `bool` via `==` (debatable) --- try-job: aarch64-gnu try-job: test-various		2025-04-24 17:19:42 +02:00
