The fast_float library provides fast header-only implementations for the C++ from_chars functions for float and double types as well as integer types. These functions convert ASCII strings representing decimal values (e.g., 1.3e10) into binary types. We provide exact rounding (including round to even). In our experience, these fast_float functions many times faster than comparable number-parsing functions from existing C++ standard libraries. It parses the character sequence [first,last) for...

HighwayHash is a fast, keyed hash function intended for scenarios where you need strong, DoS-resistant hashing without the full overhead of a general-purpose cryptographic hash. It’s designed to defeat hash-flooding attacks by mixing input with wide SIMD operations and a branch-free inner loop, so adversaries can’t cheaply craft many colliding keys. The implementation targets multiple CPU families with vectorized code paths while keeping a portable fallback, yielding high throughput across...

...The final goal of this gem is to generate JSON content that will be given to jQuery DataTables. All the data table customizations (header, tr, td, CSS classes, width, height, buttons, etc.) must take place in the javascript definition of the data table. jQuery DataTables is a very powerful tool with a lot of customization available. Take the time to read the doc.

PorTypes is a library of integer types. Currently, the library provides one unsigned integer type and one signed integer type. Both types have fixed width, which is specified at compile time via template parameters. The signed integer type uses 2's complement representation.
