Struct aws_smithy_runtime_api::client::runtime_components::SharedConfigValidator

pub struct SharedConfigValidator { /* private fields */ }

A client config validator.

Implementations

impl SharedConfigValidator

pub fn base_client_config_fn( validator: fn(_: &RuntimeComponentsBuilder, _: &ConfigBag) -> Result<(), BoxError>, ) -> Self

Creates a base client validator from a function.

A base client validator gets called upon client construction. The full config may not be available at this time (hence why it has RuntimeComponentsBuilder as an argument rather than RuntimeComponents). Any error returned from the validator function will become a panic in the client constructor.

Examples

Creating a validator function:

use aws_smithy_runtime_api::box_error::BoxError;
use aws_smithy_runtime_api::client::runtime_components::{
    RuntimeComponentsBuilder,
    SharedConfigValidator
};
use aws_smithy_types::config_bag::ConfigBag;

fn my_validation(
    components: &RuntimeComponentsBuilder,
    config: &ConfigBag
) -> Result<(), BoxError> {
    if components.sleep_impl().is_none() {
        return Err("I need a sleep_impl!".into());
    }
    Ok(())
}

let validator = SharedConfigValidator::base_client_config_fn(my_validation);
