Rust API Client

Rust integration handles uploads and file operations by wrapping Uploadcare Upload API and REST API. This comprehensive API client lets you use most of the Uploadcare features from within your Rust app.

Uploading (Upload API):

  • Upload files from local storage and URLs (up to 5 TB)
  • Multipart uploading for large files
  • Uploading network to speed uploading jobs (like CDN)

File management (REST API):

  • Get file info and perform various operations (store/delete/copy) with them
  • Work with groups of files
  • Get info about account project
  • Manage webhooks
  • Convert documents
  • Encode and transform videos

Image processing (URL API):

  • Compression
  • Geometry
  • Colors
  • Definition
  • Image and text overlays
  • Rotations
  • Recognition
  • File info
  • Proxy (fetch)

Security features:

  • Secure authentication
  • Secure uploads (signed uploads)
  • Secure delivery (signed URLs)


  • rustc 1.43
  • cargo 1.43


Ensure you have Cargo, the Rust dependency manager, installed on your system. If not, follow the installation instructions.

Open your cargo.toml file and add the following code:

uploadcare = "^0.1"


By default the full is enabled (REST and Upload API).

To reduce the code size, disable default features and enable just the APIs you use:

# Example: REST API only
uploadcare = { version = "*", default-features = false, features = ["rest"] }

Creating a client:

use ucare;
use ucare::file;
use ucare::upload;

let creds = ucare::apicreds {
    pub_key: "YOUR_PUBLIC_KEY",
    secret_key: "YOUR_SECRET_KEY",

// creating rest client
let config = ucare::RestConfig {
    sign_based_auth: true,
    api_version: ucare::RestApiVersion::v06,
let rest_client = ucare::RestClient::new(config, creds).unwrap();

// creating upload client
let config = ucare::UploadConfig {
    sign_based_upload: true,
let upload_client = ucare::UploadClient::new(config, creds).unwrap();

Usage example

For a comprehensive list of examples, check out the API documentation. Below are a few usage examples:

let file_svc = file::new_svc(&rest_client);

let file_id = "b7c1bf20-0f4c-4ba4-b3a8-a74ebc663752";
let file_info =;
println!("{}: {:?}", file_id, file_info);

let upload_svc = upload::new_svc(&upload_client);

let params = upload::FileParams {
    path: "/path/to/file".to_string(),
    name: "filename".to_string(),
    to_store: Some(upload::ToStore::Auto),
let file = upload_svc.file(params).unwrap();
println!("uploaded: {:?}",;
