This is an example of documentation generated by ZigDoc, an alternative to Zig's built-in Auto Doc feature. See also examples in other modes/formats. The project being documented here (as the example) is the Zig standard library. Private Constant

cipher_suites

Private Constant
std.crypto.tls.Client.cipher_suites
const cipher_suites = if (crypto.core.aes.has_hardware_support)
    array(u16, tls.CipherSuite, .

The priority order here is chosen based on what crypto algorithms Zig has available in the standard library as well as what is faster. Following are a few data points on the relative performance of these algorithms.
