Function varint_simd::decode_two_unsafe

pub unsafe fn decode_two_unsafe<T: VarIntTarget, U: VarIntTarget>(
    bytes: *const u8
) -> (T, U, u8, u8)

Available with target feature ssse3 only.

Decodes two adjacent varints simultaneously. Target types must fit within 16 bytes when varint encoded. Requires SSSE3 support.

For example, it is permissible to decode u32 and u32, and u64 and u32, but it is not possible to decode two u64 values with this function simultaneously.

Returns a tuple containing the two decoded values and the two lengths of bytes read for each value.

For best performance, ensure each target type is u32 or smaller.

Safety

There must be at least 16 bytes of allocated memory after the start of the pointer. Otherwise, there may be undefined behavior. Any data after the two varints are ignored. Truncated values will be returned if a varint exceeds the target type’s limit.
