Struct ServerConfigBuilder 

pub struct ServerConfigBuilder { /* private fields */ }

Builder for server configuration.

Implementations

impl ServerConfigBuilder

pub fn protocol(self, config: ProtocolConfig) -> Self

Set protocol configuration.

pub fn rate_limit(self, config: RateLimitConfig) -> Self

Set rate limiting configuration.

pub fn connection_limits(self, limits: ConnectionLimits) -> Self

Set connection limits.

pub fn required_capabilities(self, caps: RequiredCapabilities) -> Self

Set required client capabilities.

pub fn max_message_size(self, size: usize) -> Self

Set maximum message size in bytes.

Messages exceeding this size will be rejected. Default: 10MB.

pub fn origin_validation(self, config: OriginValidationConfig) -> Self

Set HTTP origin validation configuration.

pub fn allow_origin(self, origin: impl Into<String>) -> Self

Add a single allowed origin for HTTP transports.

pub fn allow_origins<I, S>(self, origins: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Add multiple allowed origins for HTTP transports.

pub fn allow_localhost_origins(self, allow: bool) -> Self

Control whether localhost origins are accepted.

pub fn allow_any_origin(self, allow: bool) -> Self

Disable origin checks entirely.

pub fn build(self) -> ServerConfig

Build the server configuration with sensible defaults.

This method always succeeds and uses defaults for any unset fields. For strict validation, use try_build().

pub fn try_build(self) -> Result<ServerConfig, ConfigValidationError>

Build the server configuration with validation.

This method validates the configuration and returns an error if any constraints are violated. Use this for stricter configuration checking in enterprise deployments.

Errors

Returns an error if:

• max_message_size is less than 1024 bytes (minimum viable message size)
• Rate limit max_requests is 0
• Rate limit window is zero
• Connection limits have all values set to 0

Example

use turbomcp_server::ServerConfig;

// Validated build - catches configuration errors
let config = ServerConfig::builder()
    .max_message_size(1024 * 1024) // 1MB
    .try_build()
    .expect("Invalid configuration");

Trait Implementations

impl Clone for ServerConfigBuilder

fn clone(&self) -> ServerConfigBuilder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ServerConfigBuilder

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

Formats the value using the given formatter.

impl Default for ServerConfigBuilder

fn default() -> ServerConfigBuilder

Returns the “default value” for a type.
