Typed results
Result[Value, Problem] tells the caller that work may fail. The caller handles both paths.
Start with a shape
Search by what a function takes and gives back. Try Result[T, E], &mut T, Array[T] -> T, server, or json.
fn find[T](items: &Array[T], keep: fn(T) -> Bool) -> Option[T]Browse modules
Build with what the community shares
Packages are published from GitHub and installed with one command. Every release is kept exactly as it was tagged.
Start here
Write a complete program
A Pudu program names its module, imports what it uses, and returns a status from main.
module Hello
import Std.Io as Io
fn main() -> Int {
let _written = Io.writeLine("Hello from Pudu!")
0
}Understand what the code promises
Pudu keeps important choices visible in function signatures and at the place where a value is used.
Explicit references
&T borrows a value for reading. &mut T asks for the exclusive right to change it, written where the call is made.
Checked patterns
match lists the shapes a value may have, so each case can be handled directly.
The library is already there
The standard library ships inside the archive. There is nothing to add to a manifest before a program can read a file, answer a request, or talk to a database.
Services
HTTP clients and servers, TLS that verifies its chain and hostname, sockets, and routing.
Data
JSON, CSV, TOML, YAML and XML, with readers that hold a flat memory peak as a file grows.
Storage
SQLite, and PostgreSQL over its own wire protocol with parameters bound rather than pasted.
Work
Workers, bounded channels, locks, and a testing module with property checks.
