Function safe_transmute::base::from_bytes_pedantic

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

Convert a byte slice into a single instance of a Copyable type.

The byte slice must have exactly the expected number of bytes to fill a single instance of a type, without trailing space.

Safety

• This function does not perform memory alignment checks. The beginning of the slice data must be properly aligned for accessing the value of type T.
• The byte data needs to correspond to a valid T value.

Failure to fulfill any of the requirements above may result in undefined behavior.

Errors

An error is returned if the slice’s length is not equal to the size of a single value T.

Examples

// Little-endian
unsafe {
    assert_eq!(from_bytes_pedantic::<u32>(&[0x00, 0x00, 0x00, 0x01])?, 0x0100_0000);
}
