## Features
|
||||
---
|
||||
### qr
|
||||
With optional feature "qr", you can use it to generate a base64 png qrcode
|
||||
With optional feature "qr", you can use it to generate a base64 png qrcode. This will enable feature `otpauth`
|
||||
### otpauth
|
||||
With optional feature "otpauth", support parsing the TOTP parameters from an `otpauth` URL, and generating an `otpauth` URL
|
||||
### serde_support
|
||||
With optional feature "serde_support", library-defined types will be Deserialize-able and Serialize-able
|
||||
With optional feature "serde_support", library-defined types `TOTP` and `Algorithm` and will be Deserialize-able and Serialize-able

Add it to your `Cargo.toml`:

```toml
|

[dependencies]
|

totp-rs = "^2.0"

[dependencies.totp-rs]

version = "^2.0"

features = ["otpauth"]
|

```
