Updating digest with web crypto

For some context, I'm updating some code that was importing from

std/hash

std/hash

std/hash

std/hash (specifically

std/hash/sha256

std/hash/sha256

std/hash/sha256

std/hash/sha256) to use

std/crypto

std/crypto

std/crypto

std/crypto since the hash submodule is long gone.

I've run up against a case where I'm not really sure what I should do to move forward. The code looks something like this:

const digest = new Sha256()

for await (const chunk of generate.chunks()) {
  digest.update(chunk)
}

if(some_condition) {
  digest.update(bonus_chunk)
}

return digest.hex()

const digest = new Sha256()

for await (const chunk of generate.chunks()) {
  digest.update(chunk)
}

if(some_condition) {
  digest.update(bonus_chunk)
}

return digest.hex()

const digest = new Sha256()

for await (const chunk of generate.chunks()) {
  digest.update(chunk)
}

if(some_condition) {
  digest.update(bonus_chunk)
}

return digest.hex()

const digest = new Sha256()

for await (const chunk of generate.chunks()) {
  digest.update(chunk)
}

if(some_condition) {
  digest.update(bonus_chunk)
}

return digest.hex()

Is this possible to handle in the web crypto standard? I'm pretty sure I should just be able to aggregate the chunks into one massive uint8array or something but I feel like there is no reason to buffer the whole thing into memory.

Any ideas?
