Crate tough

Tough is a client library for TUF repositories.

This client adheres to TUF version 1.0.0, with the following exceptions:

• Delegated roles (and TAP 3) are not yet supported.
• TAP 4 (multiple repository consensus) is not yet supported.

Testing

Unit tests are run in the usual manner: cargo test. Integration tests require docker and are disabled by default behind a feature named integ. To run all tests, including integration tests: cargo test --all-features or cargo test --features 'http,integ'.

Modules

editor

Provides a RepositoryEditor object for building and editing TUF repositories.

error

Contains the error type for this library.

key_source

Provides an abstraction over the source of a signing key. This allows signing keys to be obtained, for example, from local files or from cloud provider key stores.

schema

Provides the schema objects as defined by the TUF spec.

sign

Provides the Sign trait which abstracts over the method of signing with different key types.

Structs

DefaultTransport

A Transport that provides support for both local files and, if the http feature is enabled, HTTP-transported files.

FilesystemTransport

Provides a Transport for local files.

Limits

Limits used when fetching repository metadata.

Repository

A TUF repository.

RepositoryLoader

A builder for settings with which to load a Repository. Required settings are provided in the RepositoryLoader::new function. Optional parameters can be added after calling new. Finally, call RepositoryLoader::load to load the Repository.

TargetName

Represents the name of a target in the repository. Path-like constructs are resolved (e.g. foo/../bar becomes bar). Certain unsafe names are rejected when constructing a TargetName. Unsafe names include:

TransportError

The error type that Transport::fetch returns.

Enums

ExpirationEnforcement

Represents whether a Repository should fail to load when metadata is expired (Safe) or whether it should ignore expired metadata (Unsafe). Only use Unsafe if you are sure you need it.

Prefix

Use this enum to specify whether or not we should include a prefix in the target name when saving a target.

TransportErrorKind

The kind of error that the transport object experienced during fetch.

Traits

Transport

A trait to abstract over the method/protocol by which files are obtained.
