Struct ServerCapabilitiesBuilder 

pub struct ServerCapabilitiesBuilder<S = ServerCapabilitiesBuilderState> { /* private fields */ }

Const-generic ServerCapabilities builder with compile-time validation

This builder ensures that capability-specific methods are only available when the corresponding capability is enabled, providing compile-time safety with compile-time validation.

Implementations

impl ServerCapabilitiesBuilder

pub fn new() -> Self

Create a new ServerCapabilities builder

impl<S> ServerCapabilitiesBuilder<S>

pub fn build(self) -> ServerCapabilities

Build the final ServerCapabilities

Consumes the builder and returns the configured ServerCapabilities. All compile-time validations have been enforced during building.

pub fn with_strict_validation(self) -> Self

TurboMCP Extension: Enable strict validation mode

When enabled, the builder will perform additional runtime validations on top of the compile-time guarantees.

pub fn with_negotiator(self, negotiator: CapabilityNegotiator) -> Self

TurboMCP Extension: Set capability negotiator

Integrates with TurboMCP’s sophisticated capability negotiation system for advanced client-server capability matching.

pub fn validate(&self) -> Result<(), String>

TurboMCP Extension: Validate capability configuration

Performs additional runtime validation to ensure the capability configuration makes sense in the current context.

pub fn summary(&self) -> String

Get a summary of enabled capabilities

Returns a human-readable summary of which capabilities are enabled.
