Enum ChangeReason 

pub enum ChangeReason {
    NoCachedBuild,
    InputHashChanged {
        from: Sha256,
        to: Sha256,
    },
    UpstreamMoved {
        dep: ActionId,
    },
}

Why a given action is considered stale and needs to re-run.

Variants

NoCachedBuild

The cache has no prior build event for this action.

InputHashChanged

The action was previously built, but its current input hash differs.

Fields

from: Sha256

Hash recorded in the last successful build.

to: Sha256

Hash computed for the current run.

UpstreamMoved

The action’s own hash is unchanged, but a transitive dependency is stale.

Fields

dep: ActionId

First stale dependency encountered (deterministic via deps order).
