Struct RequestOptions 

pub struct RequestOptions {
    pub request_timeout: Duration,
    pub max_line_length: usize,
    pub channel_capacity: usize,
    pub retry_delay: Option<Duration>,
    pub max_retries: Option<usize>,
    pub custom_headers: Option<HashMap<String, String>>,
    pub request_header_provider: Option<Arc<dyn Fn(&str) -> Option<HeaderMap> + Send + Sync>>,
}

Fields

request_timeout: Duration

max_line_length: usize

channel_capacity: usize

retry_delay: Option<Duration>

max_retries: Option<usize>

custom_headers: Option<HashMap<String, String>>

request_header_provider: Option<Arc<dyn Fn(&str) -> Option<HeaderMap> + Send + Sync>>

Optional hook invoked with the raw JSON-RPC payload of each outgoing POST, returning extra HTTP headers to attach to that single request.

Unlike custom_headers (static, applied to every request), this enables per-request headers computed from the message being sent — e.g. SEP-2243 Mcp-Param-* tool-parameter mirroring, rotating bearer tokens, or distributed-tracing headers.
