instance Lake.instInhabitedArtifact : Inhabited Artifact

Equations

• Lake.instInhabitedArtifact = { default := { path := default, name := default, mtime := default, hash := default } }

instance Lake.instReprArtifact : Repr Artifact

Equations

• Lake.instReprArtifact = { reprPrec := Lake.reprArtifact✝ }

def Lake.Artifact.withName (name : String) (self : Artifact) : Artifact

Sets the name of the artifact.

Equations

• Lake.Artifact.withName name self = { path := self.path, name := name, mtime := self.mtime, hash := self.hash }

def Lake.Artifact.useLocalFile (path : System.FilePath) (self : Artifact) : Artifact

Sets the name and path of the artifact using the file outside the Lake artifact cache.

Equations

• Lake.Artifact.useLocalFile path self = { path := path, mtime := self.mtime, hash := self.hash }

def Lake.Artifact.trace (self : Artifact) : BuildTrace

The build trace formed from this single artifact.

Equations

• self.trace = { caption := self.name, hash := self.hash, mtime := self.mtime }
