Enum ToolchainError 

#[non_exhaustive]
pub enum ToolchainError {
    NotInstalled,
    UnsupportedOperation,
}

Error caused by methods in the toolchain moodule.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotInstalled

The toolchain is not installed in the workspace, but the called method requires it to be present. Use the Toolchain::Install method to install it inside the workspace.

UnsupportedOperation

Not every method can be called with every kind of toolchain. If you receive this error please check the documentation of the method you’re calling to see which toolchains can you use with it.
