Enum ResolverRequest

pub enum ResolverRequest {
    Resolve {
        name: String,
        responder: ResolverResolveResponder,
    },
}

An interface for resolving names to executables and library loaders.

An executable itself is often not sufficient to create a working process because many executables also load shared libraries. On Fuchsia, there is no global pool of shared libraries. Instead, every process has an associated fuchsia.ldsvc.Loader, which provides access to a private pool of shared libraries appropriate for that process.

This interface provides a protocol for resolving a name into both the zx.Handle:VMO for the executable and the fuchsia.ldsvc.Loader for its associated shared libraries.

This interface is rarely used directly. Instead, fdio_spawn and fdio_spawn_etc use this interface internally when they try to run a file with a #!resolve directive.

Variants

Resolve

Resolves the given name to an executable and an shared library loader.

If present, the executable is suitable for use as the executable property of LaunchInfo – in particular, it will have ZX_RIGHT_EXECUTE. If present, the ldsvc is suitable for use as the PA_LDSVC_LOADER handle when launching the process.

For example, the resolver might locate the given name inside a package and return the executable binary from the package as well as a shared library loader scoped to that package.
