Struct RuntimeConfig 

#[non_exhaustive]
pub struct RuntimeConfig {
    pub auto_initialized: bool,
    pub max_concurrent_requests: usize,
    pub outbound_request_timeout: Duration,
    pub default_task_ttl_ms: Option<u64>,
    pub default_task_poll_interval_ms: Option<u64>,
    pub task_status_notifications: bool,
}

Server runtime configuration.

Marked #[non_exhaustive]: the runtime gains settings over time, and with an exhaustive struct every one of those additions is a breaking change for any downstream struct-literal construction. Build one with new/default and the setters below, which keeps later additions compatible. (Doing this before 1.0 is the whole point — after 1.0 the type would be stuck exhaustive.)

use mcpkit_server::RuntimeConfig;
let config = RuntimeConfig::new()
    .max_concurrent_requests(32)
    .task_status_notifications(false);

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

auto_initialized: bool

Whether to automatically send initialized notification.

max_concurrent_requests: usize

Maximum concurrent requests to process.

outbound_request_timeout: Duration

How long a server-initiated request (e.g. elicitation, sampling) waits for the client’s response before failing.

default_task_ttl_ms: Option<u64>

Retention (milliseconds) applied to a task whose tools/call omits a ttl. None means unlimited (such tasks are never TTL-evicted).

default_task_poll_interval_ms: Option<u64>

Suggested polling interval (milliseconds) stamped on tasks the runtime creates, surfaced to the client as pollInterval. None (the default) leaves it absent, which is legal — the field is a hint, so a requestor that receives none picks its own rate.

task_status_notifications: bool

Whether to publish notifications/tasks/status when a task changes status. Optional per spec (“Receivers MAY send”), so this can be turned off for a chattier-than-wanted session without affecting conformance; the requesting peer must not rely on receiving it either way.

Implementations

impl RuntimeConfig

pub fn new() -> Self

Create a runtime configuration with default values.

pub const fn auto_initialized(self, yes: bool) -> Self

Whether to automatically send the initialized notification.

pub const fn max_concurrent_requests(self, max: usize) -> Self

Maximum number of requests processed concurrently.

pub const fn outbound_request_timeout(self, timeout: Duration) -> Self

How long a server-initiated request waits for the client’s response.

pub const fn default_task_ttl_ms(self, ttl_ms: Option<u64>) -> Self

Retention applied to a task whose tools/call omits a ttl. None means unlimited.

pub const fn default_task_poll_interval_ms( self, poll_interval_ms: Option<u64>, ) -> Self

Suggested polling interval (milliseconds) for tasks the runtime creates.

pub const fn task_status_notifications(self, yes: bool) -> Self

Whether to publish notifications/tasks/status on task transitions.
