Function safe_transmute::trivial::transmute_trivial_pedantic

pub unsafe fn transmute_trivial_pedantic<T: TriviallyTransmutable>(
    bytes: &[u8]
) -> Result<T, Error<'_, u8, T>>

Transmute a byte slice into a single instance of a trivially transmutable type.

The byte slice must have exactly enough bytes to fill a single instance of a type.

Errors

An error is returned in one of the following situations:

• The data does not have a memory alignment compatible with T. You will have to make a copy anyway, or modify how the data was originally made.
• The data does not have enough bytes for a single value T.
• The data has more bytes than those required to produce a single value T.

Safety

This function invokes undefined behavior if the data does not have a memory alignment compatible with T. If this cannot be ensured, you will have to make a copy of the data, or change how it was originally made.

Examples

// Little-endian
unsafe {
    assert_eq!(transmute_trivial_pedantic::<u16>(&[0x0F, 0x0E])?, 0x0E0F);
}
