WebDec 3, 2024 · Sounds logical, but I don't know how to "cast" the pixel into the array. It is not safe to convert a reference of u8 into a reference of u32.And if the compiler let you assign a value of type u32 into a u8, it have likely not have worked as you intended, since the value would have to be truncated into a single component so that it would fit in a single slice …WebAug 20, 2012 · Probably an easier way to cast is to use union with a long long member: typedef unsigned long long int UINT64; typedef unsigned long GT_U32; typedef unsigned short GT_U16; typedef unsigned char GT_U8; typedef union { GT_U8 c [8]; GT_U16 s [4]; GT_U32 l [2]; UINT64 ll; } GT_U64; Then, simply accessing ll will get the 64-bit value …

WebMay 29, 2015 · 1 Answer. Assuming you want to convert a vector of 16 x 8 bit ints to four vectors of 4 x 32 bit ints, you can do this by first unpacking to 16 bits and then again to 32 bits: // load 8 bit vector uint8x16_t v = vld1q_u8 (p); // load vector of 16 x 8 bits ints from p // unpack to 16 bits int16x8_t vl = vreinterpretq_s16_u16 (vmovl_u8 (vget_low ... WebMar 10, 2024 · Rust strings are not NUL-terminated like most C functions expect. You can convert a &str to *const u8 by using &s.as_bytes()[0] as *const u8 or by using s.as_ptr(), but that will not be valid to pass to any C function expecting a NUL-terminated string.. Instead, you probably need to use CString which will copy the string to a buffer and add a NUL …WebApr 29, 2024 · alice April 29, 2024, 1:34pm #6.
