Simple string

Examples

Value
"+OK\r\n"
Build
use resp_protocol::SimpleString;

let simple_string: SimpleString = SimpleString::new(b"OK");
Parse
use resp_protocol::SimpleString;

let string: &str = "+OK\r\n";
let simple_string: SimpleString = SimpleString::parse(string.as_bytes(), &mut 0, &string.len()).unwrap();

Error

Examples

Value
"-ERROR\r\n"
Build
use resp_protocol::Error;

let error: Error = Error::new(b"ERROR");
Parse
use resp_protocol::Error;

let string: &str = "-ERROR\r\n";
let error: Error = Error::parse(string.as_bytes(), &mut 0, &string.len()).unwrap();

Integer

Examples

Value
":100\r\n"
Build
use resp_protocol::Integer;

let integer: Integer = Integer::new(-100i64);
Parse
use resp_protocol::Integer;

let string: &str = ":-100\r\n";
let integer: Integer = Integer::parse(string.as_bytes(), &mut 0, &string.len()).unwrap();

Bulk string

Examples

Value
"$6\r\nfoobar\r\n"
Build
use resp_protocol::BulkString;

let bulk_string: BulkString = BulkString::new(b"foobar");
Parse
use resp_protocol::BulkString;

let string: &str = "$6\r\nfoobar\r\n";
let bulk_string: BulkString = BulkString::parse(string.as_bytes(), &mut 0, &string.len()).unwrap();

Array

Examples

Value
"*0\r\n"                            // empty array
"*2\r\n$3\r\nfoo\r\n$3\r\nbar\r\n"  // bulk strings array
"*2\r\n:1\r\n$6\r\nfoobar\r\n"      // mixed types array
Build
use resp_procotol::{Array, ArrayBuilder, RespType, Integer, BulkString};

let mut array_builder: ArrayBuilder = ArrayBuilder::new();
array_builder.insert(RespType::Integer(Integer::new(100)));
array_builder.insert(RespType::BulkString(BulkString::new(b"foobar")));

let array: Array = array_builder.build();
println!("{:?}", array); // Array(b"*2\r\n:100\r\n$6\r\nfoobar\r\n")
Parse
use resp_protocol::Array;

let string = "*2\r\n$3\r\nfoo\r\n$3\r\nbar\r\n";
let array = Array::parse(string.as_bytes(), &mut 0, &string.len()).unwrap();
println!("{:?}", array); // Array(b"*2\r\n$3\r\nfoo\r\n$3\r\nbar\r\n")
