Re: [swift-users] raw buffer pointer load alignment

For context, the problem I’m trying to solve is efficiently parsing JPEG chunks. This means reading each chunk of the JPEG from a file into a raw buffer pointer, and then parsing the chunk according to its expected layout. For example, a frame header chunk looks like this: 0 1

Re: [swift-users] raw buffer pointer load alignment

yikes there’s no less verbose way to do that? and if the type isn’t an integer there’s no way to avoid the default initialization? Can this be done with opaques or something? On Wed, Nov 8, 2017 at 7:04 PM, Johannes Weiß wrote: > Hi Kelvin, > > > On 8 Nov 2017, at 4:54 pm, Kelvin Ma via swift-us

[swift-users] raw buffer pointer load alignment

According to the docs , the load(fromByteOffset:as:) method requires the instance to be “properly aligned” Does that mean if I have raw data meant to be interpreted as 0 1 2 3 4 5 6 [
