The next block's header consists of 093f, broken down as 09 16 ⇒ off h =000 2,len−4=010 2;type=01 2: type 1 indicates a "copy with 1-byte offset": the length to copy works out to 010 2 +4=6 bytes, and the offset is an 11-bit integer whose top bits are off h and whose low bits are the next byte: 3f, so {off h}{3f 16}=00000111111 2 =63.
It supports “zero-copy” deserialization, so that accessing the serialized data does not require first copying it into a separate part of memory. This makes accessing data in these formats much faster than data in formats requiring more extensive processing, such as JSON , CSV , and in many cases Protocol Buffers.
This is important in cases where values of a field cannot be known until the content has been produced, such as when the content of the message must be digitally signed. Without chunked encoding, the sender would have to buffer the content until it was complete in order to calculate a field value and send it before the content.
A schema for a particular use of protocol buffers associates data types with field names, using integers to identify each field. (The protocol buffer data contains only the numbers, not the field names, providing some bandwidth/storage savings compared with systems that include the field names in the data.)
The most significant difference between Node.js and PHP is that most functions in PHP block until completion (commands execute only after previous commands finish), while Node.js functions are non-blocking (commands execute concurrently and use callbacks to signal completion or failure), [29] thus opening up new attack surfaces that are ...
In computer science, a data buffer (or just buffer) is a region of memory used to store data temporarily while it is being moved from one place to another. Typically, the data is stored in a buffer as it is retrieved from an input device (such as a microphone) or just before it is sent to an output device (such as speakers); however, a buffer may be used when data is moved between processes ...
concatjson concatenated JSON streaming parser/serializer module for Node.js; json-stream-es is a JavaScript/TypeScript library (frontend and backend) that can create and read concatenated JSON documents. Jackson (API) can read and write concatenated JSON content. jq lightweight flexible command-line JSON processor; Noggit Solr's streaming JSON ...
A packet-switched network transmits data that is divided into units called packets.A packet comprises a header (which describes the packet) and a payload (the data). The Internet is a packet-switched network, and most of the protocols in this list are designed for its protocol stack, the IP protocol suite.
