Functions | |
| template<typename Storage , std::size_t BitOffset, std::size_t Width> | |
| constexpr Storage | esi::detail::readUnsignedBits (const uint8_t *bytes) |
Read Width bits starting at BitOffset (LSB-first within bytes) and return them zero-extended in Storage. | |
| template<typename Signed , std::size_t BitOffset, std::size_t Width> | |
| constexpr Signed | esi::detail::readSignedBits (const uint8_t *bytes) |
Read Width bits starting at BitOffset (LSB-first) and sign-extend into the signed integer type Signed. | |
| template<typename Storage , std::size_t BitOffset, std::size_t Width> | |
| constexpr void | esi::detail::writeUnsignedBits (uint8_t *bytes, Storage value) |
Write the low Width bits of value into bytes starting at BitOffset (LSB-first). | |
| template<typename Signed , std::size_t BitOffset, std::size_t Width> | |
| constexpr void | esi::detail::writeSignedBits (uint8_t *bytes, Signed value) |
| Convenience overload for signed values. | |
| template<std::size_t BitOffset, std::size_t Width> | |
| constexpr void | esi::detail::copyBitsIn (const uint8_t *src, uint8_t *dst) |
Copy Width bits out of src starting at BitOffset into dst packed LSB-first from bit 0. | |
| template<std::size_t BitOffset, std::size_t Width> | |
| constexpr void | esi::detail::copyBitsOut (uint8_t *dst, const uint8_t *src) |
Inverse of copyBitsIn: take Width bits packed LSB-first from bit 0 of src and write them into dst starting at BitOffset. | |
