Struct ReadinessSnapshot 

pub struct ReadinessSnapshot {
    pub command: String,
    pub args: Vec<String>,
    pub elapsed_ms: u64,
    pub ms_to_first_response: Option<u64>,
    pub ms_to_first_nonempty: Option<u64>,

    pub response_count: u64,
    pub nonempty_count: u64,
    pub failure_count: u64,
}

Plain-old-data readiness view for callers (MCP handlers, bench scripts). All milliseconds are relative to session.started_at.

Implementations

impl ReadinessSnapshot

pub fn is_ready(&self) -> bool

A session is ready when it has returned at least one non-empty response. Zero-result responses are not enough — pyright and rust-analyzer both emit [] while the project is being walked, and an agent that unblocks on the first empty reply ends up issuing the real query before indexing is done (which is the failure mode P0-4 was created to stop).

pub fn is_alive(&self) -> bool

A session is alive when its handshake round-tripped at least once. Alive-but-not-ready means the LSP is up but has not produced usable data yet.
