Resolve a name to an immutable resource record

Separates the two things that must not be conflated: an immutable resource record, and the mutable channel that maps a logical name onto one. This function walks the channel; everything downstream deals only in records.

Usage

resolve_resource(
  name,
  package = NULL,
  registry = NULL,
  policy = NULL,
  version = NULL
)

Arguments

name

Resource name.

package

Declaring package. Ignored when registry is supplied.

registry

A registry() object, for standalone use.

policy

Resolution policy, defaulting to getaca_policy().

version

Optional explicit version, bypassing channel resolution.

Value

A list with id, record, policy, source, digest, created and auth. policy is the one actually in force, after the argument, the session setting, the registry default and the check clamp have been resolved. digest identifies the registry state that answered, and created says when that state was published, or NA for a declaration that was built in the session rather than read from a file. auth is the credential declaration, taken from the registry the package ships.
