# [Sqids Rust](https://sqids.org/rust)

[Sqids](https://sqids.org/rust) (*pronounced "squids"*) is a small library that lets you **generate unique IDs from numbers**. It's good for link shortening, fast & URL-safe ID generation and decoding back into numbers for quicker database lookups.
Features:
- **Encode multiple numbers** - generate short IDs from one or several non-negative numbers
- **Quick decoding** - easily decode IDs back into numbers
- **Unique IDs** - generate unique IDs by shuffling the alphabet once
- **ID padding** - provide minimum length to make IDs more uniform
- **URL safe** - auto-generated IDs do not contain common profanity
- **Randomized output** - Sequential input provides nonconsecutive IDs
- **Many implementations** - Support for [40+ programming languages](https://sqids.org/)
## 🧰 Use-cases
Good for:
- Generating IDs for public URLs (eg: link shortening)
- Generating IDs for internal systems (eg: event tracking)
- Decoding for quicker database lookups (eg: by primary keys)
Not good for:
- Sensitive data (this is not an encryption library)
- User IDs (can be decoded revealing user count)
## 🚀 Getting started
Add using cargo:
```bash
cargo add sqids
```
## 👩💻 Examples
Simple encode & decode:
```rust
# use sqids::Sqids;
let sqids = Sqids::default();
let id = sqids.encode(&[1, 2, 3])?; // "86Rf07"
let numbers = sqids.decode(&id); // [1, 2, 3]
# Ok::<(), sqids::Error>(())
```
> **Note**
> 🚧 Because of the algorithm's design, **multiple IDs can decode back into the same sequence of numbers**. If it's important to your design that IDs are canonical, you have to manually re-encode decoded numbers and check that the generated ID matches.
Enforce a *minimum* length for IDs:
```rust
# use sqids::Sqids;
let sqids = Sqids::builder()
.min_length(10)
.build()?;
let id = sqids.encode(&[1, 2, 3])?; // "86Rf07xd4z"
let numbers = sqids.decode(&id); // [1, 2, 3]
# Ok::<(), sqids::Error>(())
```
Randomize IDs by providing a custom alphabet:
```rust
# use sqids::Sqids;
let sqids = Sqids::builder()
.alphabet("FxnXM1kBN6cuhsAvjW3Co7l2RePyY8DwaU04Tzt9fHQrqSVKdpimLGIJOgb5ZE".chars().collect())
.build()?;
let id = sqids.encode(&[1, 2, 3])?; // "B4aajs"
let numbers = sqids.decode(&id); // [1, 2, 3]
# Ok::<(), sqids::Error>(())
```
Prevent specific words from appearing anywhere in the auto-generated IDs:
```rust
# use sqids::Sqids;
let sqids = Sqids::builder()
.blocklist(["86Rf07".to_string()].into())
.build()?;
let id = sqids.encode(&[1, 2, 3])?; // "se8ojk"
let numbers = sqids.decode(&id); // [1, 2, 3]
# Ok::<(), sqids::Error>(())
```
