Enum SessionPlacement 

pub enum SessionPlacement {
    Named(Placement),
    Fake,
}

Where a session of this client runs: the placement the machine resolved, or the in-process fake runtime.

Placement is a property of the machine and comes from the workspace config.toml or from ONLYNE_BACKEND; a drive is a property of the runtime and comes from the role’s spec. fake is the backend that owns no process and needs no external tool, which is how the scenario suite and every e2e case run a real client on a machine with no terminal host at all. Only the environment and an embedding that resolved the placement itself can name it: a workspace config names a placement, and a runtime that starts nothing is not one an operator should reach by typo.

Implementations

impl SessionPlacement

pub fn parse(name: &str) -> Option<Self>

Two pre-split spellings are accepted here and nowhere else: fake selects the in-process test runtime, and exec is the name a v1 ONLYNE_BACKEND used for a session the client runs in the background, which is the headless placement. A workspace config names neither: its key is placement, and the five names that key accepts are the ones onlyne_config::PLACEMENT_NAMES lists.

pub fn as_str(self) -> &'static str

pub fn named(self) -> Option<Placement>

The placement itself, None for the in-process runtime, which names no place on the machine.
