Enum ServerStatus 

pub enum ServerStatus {
    Running,
    Stopped,
    Crashed,
    Restarting,
    Disabled,
    FailedToStart,
}

Available on crate feature tools only.

Current lifecycle state of a managed MCP server.

Transitions:

• Stopped → Running (on successful start)
• Stopped → FailedToStart (on start failure)
• Running → Stopped (on manual stop or shutdown)
• Running → Crashed (on health check failure or unexpected exit)
• Running → Restarting (during restart)
• Crashed → Restarting (on auto-restart)
• Restarting → Running (on successful restart)
• Restarting → FailedToStart (on restart failure)
• Disabled (set at construction, no transitions out unless re-configured)

Variants

Running

The server process is running and the MCP connection is active.

Stopped

The server has been stopped (manually or via shutdown).

Crashed

The server process exited unexpectedly or a health check failed.

Restarting

The server is in the process of being restarted.

Disabled

The server configuration has disabled: true; it will not be started.

FailedToStart

The server failed to start (spawn failure, handshake failure, or max restarts exceeded).

Trait Implementations

impl Clone for ServerStatus

fn clone(&self) -> ServerStatus

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ServerStatus

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ServerStatus

fn deserialize<__D>( __deserializer: __D, ) -> Result<ServerStatus, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for ServerStatus

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ServerStatus

fn eq(&self, other: &ServerStatus) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ServerStatus

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
