Enum TargetAction 

#[non_exhaustive]
pub enum TargetAction {
    Install,
    Update {
        from: Option<String>,
    },
    Skip,
    DriftedSkip {
        installed: String,
    },
    RefuseNewer {
        installed: String,
    },
    Downgrade {
        from: String,
    },
}

The action to take for a single target platform during an install.

Non-exhaustive

This enum is #[non_exhaustive]: new action variants may be added in future minor releases. Embedders should render actions via the Display impl on Report/InstallPlan or match on specific variants they care about with a catch-all _ arm. The will_write() and is_blocked() helpers cover the two common branching points without requiring exhaustive matching.

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.

Install

First-time install (no existing copy).

Update

Overwrite an older installed version.

Fields

from: Option<String>

The previously installed version string (if known).

Skip

Already installed at the same version and checksum — nothing to do.

DriftedSkip

Same version but the on-disk content differs from the bundled content, and force was not requested.

Fields

installed: String

RefuseNewer

The installed version is newer than the bundled version, and force was not requested.

Fields

installed: String

Downgrade

The installed version is newer, but force was requested — downgrade.

Fields

from: String
