Convert QByteArray to vector<uint8_t>

[Damian7546]

Hi,

I need help with convert QByteArray to vector<uint8_t>.
Is there any simple way to do it ?

Does this work:

std::vector<uint8_t> c(bytes.constData(), bytes.constData() + bytes.size());

uint8_t should be same type as unsigned char.

Hi,

something like this:

for(const char c : array)
    vector<<uint8_t(c);

@mpergand
That's really slow! Surely this is worth doing (somehow) without iterating?

[mpergand]

@JonB said in Convert QByteArray to vector<uint8_t>:

std::vector<uint8_t> c(bytes.constData(), bytes.constData() + bytes.size());

Good catch,
does not seem possible with QVector ?

@mpergand
Sorry, not sure what you mean? You mean that code would not work to convert to QVector<uint8_t> instead of std::vector<uint8_t>, is that it?

@JonB nice solution. Is std::vector<uint8_t> c( bytes.begin(), bytes.end() ) more C++ style-ish?;
