Crate cloudinary

At the moment, there is only half-backed upload and transformation functionality, but if you need more, please let me know.

Upload an image

Upload can be done from different sources:

• local file
• remote file
• data url rfc2397

Local file

use std::collections::BTreeSet;
use cloudinary::upload::{Source, Upload, OptionalParameters};

let upload = Upload::new("api_key".to_string(), "cloud_name".to_string(), "api_secret".to_string() );
let options = BTreeSet::from([OptionalParameters::PublicId("file.jpg".to_string())]);
let result = upload.image(Source::Path("./image.jpg".into()), &options);

Remote file

use std::collections::BTreeSet;
use cloudinary::upload::{Source, Upload, OptionalParameters};

let image_url = "https://upload.wikimedia.org/wikipedia/commons/c/ca/1x1.png";
let options = BTreeSet::from([OptionalParameters::PublicId("1x1.png".to_string())]);
let upload = Upload::new("api_key".to_string(), "cloud_name".to_string(), "api_secret".to_string() );
let result = upload.image(Source::Path("./image.jpg".into()), &options);

Data url

use std::collections::BTreeSet;
use cloudinary::upload::{Source, Upload, OptionalParameters};

let data_url = "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==";
let options = BTreeSet::from([OptionalParameters::PublicId("1x1.png".to_string())]);
let upload = Upload::new("api_key".to_string(), "cloud_name".to_string(), "api_secret".to_string() );
let result = upload.image(Source::DataUrl(data_url.to_string()), &options);

Destroy an asset by publicID

use cloudinary::upload::Upload;
let upload = Upload::new("api_key".to_string(), "cloud_name".to_string(), "api_secret".to_string() );
let result = upload.destroy("publicID");

Transform an image

Currently supported transformations:

• Resize
• Crop
• Pad

Resizing an image:

use cloudinary::transformation::{
    Transformations::Resize, ResizeMode::ScaleByWidth, Image
};

let image = Image::new("test".into(), "path/name.png".into())
    .add_transformation(Resize(ScaleByWidth{ width:100, ar: None, liquid:None}));
assert_eq!(
    image.to_string(),
    "https://res.cloudinary.com/test/image/upload/c_scale,w_100/path/name.png"
);

Cropping an image:

use cloudinary::transformation::{
   Transformations::Crop, CropMode::FillByWidth, Image
};

let image = Image::new("test".into(), "path/name.png".into())
    .add_transformation(Crop(FillByWidth{ width:100, ar: None, gravity: None}));

assert_eq!(
    image.to_string(),
    "https://res.cloudinary.com/test/image/upload/c_fill,w_100/path/name.png"
);

Padding an image:

use cloudinary::transformation::{
  Transformations::Pad, PadMode::PadByWidth, Image
};

let image = Image::new("test".into(), "path/name.png".into())
    .add_transformation(Pad(PadByWidth{ width:100, ar: None, background: None, gravity: None}));
assert_eq!(
   image.to_string(),
   "https://res.cloudinary.com/test/image/upload/c_pad,w_100/path/name.png"
);

Get Image from URL

Unofficial api. This is not supported by Cloudinary, and can break at any time. Officially you should use public_id that you get from upload.

Support

use cloudinary::transformation::Image;
use url::Url;
let image = Image::try_from(
    Url::parse("https://res.cloudinary.com/test/image/upload/path/name.png").unwrap()
).unwrap();
assert_eq!(image.to_string(), "https://res.cloudinary.com/test/image/upload/path/name.png");

Get a list of all assets with a given tag

use cloudinary::tags::get_tags;
let tags = get_tags("cloud_name".into(), "tag_name".into()).await;

Development

Due to differences in default upload result shape in different accounts, two sets of credentials must be present in .env for tests to succeed.

CLOUDINARY_API_SECRET=***
CLOUDINARY_API_KEY=***
CLOUDINARY_CLOUD_NAME=***

CLOUDINARY_API_SECRET_1=***
CLOUDINARY_API_KEY_1=***
CLOUDINARY_CLOUD_NAME_1=***
