Connection settings for a [`HyperClient`](https://docs.kinetica.com/content/api/rust/hyper_client/struct.HyperClient).[`HttpClientConfig::from_options`](https://docs.kinetica.com/content/api/rust/hyper_client/struct.HttpClientConfig#method.from_options) derives them from `KineticaOptions`. Fields `bypass_ssl_cert_check: bool` Accept any server certificate. See \[`AcceptAnyServerCert`] for what this gives up. `trust_store: Option>` The trust store to trust servers by, in place of the system’s roots `connect_timeout: Option` Limit on establishing a connection; `None` waits indefinitely. `request_timeout: Option` Read timeout: the limit on the wait for a response once the request has been sent, and then on each read of its body; the upload is not limited. `None` waits indefinitely. `max_connections_per_host: usize` Most requests in flight to one host at a time; also the number of idle connections kept per host for reuse. At least 1. `max_total_connections: usize` Most requests in flight across all hosts at a time. At least 1. `connection_request_timeout: Duration` How long a request waits for a free connection when a limit above is reached, before failing as a connection error. `max_retries: usize` How many times an API request is retried, at once and on the same server: when sending it fails without a response (the connection is refused, reset or closed, the host is unknown, or no response arrives within the timeout), or the response is a 502 or 503. A connect timeout, a TLS failure or a failure reading the response body is not retried, and neither are health checks. `tcp_keep_alive: bool` Whether connections send TCP keep-alive probes: on by default with the operating system’s timings. `tcp_keep_idle: u32` Seconds a connection idles before the first probe; 0 keeps the system’s. `tcp_keep_interval: u32` Seconds between probes; 0 keeps the system’s. `tcp_keep_count: u32` Probes before the connection is dropped; 0 keeps the system’s. `connection_time_to_live: Duration` How long after its opening a connection may be reused: [`CONNECTION_TIME_TO_LIVE`](https://docs.kinetica.com/content/api/rust/hyper_client/index#constant.CONNECTION_TIME_TO_LIVE), one minute, by default. ## Implementations [Source](https://github.com/kineticadb/kinetica-api-rust/blob/master/crates/gpudb-api/src/hyper_client.rs#L118-L147) impl [HttpClientConfig](https://docs.kinetica.com/content/api/rust/hyper_client/struct.HttpClientConfig.md) [Source](https://github.com/kineticadb/kinetica-api-rust/blob/master/crates/gpudb-api/src/hyper_client.rs#L129-L146) pub fn [from\_options](#method.from_options)(options: &[KineticaOptions](https://docs.kinetica.com/content/api/rust/gpudb/struct.KineticaOptions.md)) -> Self Takes the connection settings from `options`:
  • `server_connection_timeout` is the connect timeout,
  • `timeout` is the request timeout,
  • `max_connections_per_host` and `max_total_connections` cap the requests in flight.
A timeout of 0 means no limit. A connection limit below 1, which `Kinetica` refuses, is raised to 1 here for a configuration built some other way. ## Trait Implementations [Source](https://github.com/kineticadb/kinetica-api-rust/blob/master/crates/gpudb-api/src/hyper_client.rs#L59) impl [Clone](https://doc.rust-lang.org/1.98.1/core/clone/trait.Clone.html) for [HttpClientConfig](https://docs.kinetica.com/content/api/rust/hyper_client/struct.HttpClientConfig.md) [Source](https://github.com/kineticadb/kinetica-api-rust/blob/master/crates/gpudb-api/src/hyper_client.rs#L59) fn [clone](https://doc.rust-lang.org/1.98.1/core/clone/trait.Clone.html#tymethod.clone)(\&self) -> [HttpClientConfig](https://docs.kinetica.com/content/api/rust/hyper_client/struct.HttpClientConfig.md) Returns a duplicate of the value.
