Enum InstallError 

pub enum InstallError {
    AlreadyBuilt {
        dir: PathBuf,
        earlier: String,
    },
    Unreadable {
        dir: PathBuf,
        source: Error,
    },
}

Why an explicit installation was refused.

Variants

AlreadyBuilt

The registry was already built — from a different directory, or from none — before this directory was offered. The order is the rule: a host installs its plugin directory before anything resolves a name.

Fields

dir: PathBuf

The directory that was refused.

earlier: String

" from <dir>" when a directory had been installed, else empty.

Unreadable

The directory cannot be read at all — it is missing, or not a directory, or not readable by this process.

Fields

dir: PathBuf

The directory that was offered.

source: Error

What the filesystem said.
