NewConstraints creates a Constraints based on a version.Constraints.

NewLocalPluginCache returns a PluginCache that caches plugins in a given local directory.

ResolvePluginPaths takes a list of paths to plugin executables (as returned by e.g.

ErrorChecksumVerification indicates that the current checksum of the provider plugin has changed since the initial release and is not trusted to download.

ErrorMissingChecksumVerification indicates that either the provider distribution is missing the SHA256SUMS file or the checksum file does not contain a checksum for the binary plugin.

ErrorNoSuchProvider indicates that no provider exists with a name given.

ErrorNoSuitableVersion indicates that a suitable version (meeting given constraints) is not available.

ErrorNoVersionCompatible indicates that all of the available versions that otherwise met constraints are not compatible with the current version of Terraform.

ErrorNoVersionCompatibleWithPlatform indicates that all of the available versions that otherwise met constraints are not compatible with the requested platform.

ErrorPublicRegistryUnreachable indicates that the network was unable to connect to the public registry in particular, so we can show a link to the statuspage.

ErrorServiceUnreachable indicates that the network was unable to connect to the registry service.

ErrorSignatureVerification indicates that the digital signature for a provider distribution could not be verified for one of the following reasons: missing signature file, missing public key, or the signature was not signed by any known key for the publisher.

ErrorVersionIncompatible indicates that all of the versions within the constraints are not compatible with the current version of Terrafrom, though there does exist a version outside of the constaints that is compatible.

Error is a type used to describe situations that the caller must handle since they indicate some form of user error.

A PluginMetaSet is a set of PluginMeta objects meeting a certain criteria.
