#GresIQ

GresIQ is smbCloud's managed PostgreSQL bootstrap crate for small and medium businesses. It is designed around the product shape teams expect from Neon, Prisma Postgres, and similar services:

• branch-aware environments
• autoscaling-friendly connection defaults
• safe connection-string handling
• a small Rust API that can sit underneath CLI, desktop, web, or future bindings

This crate is the Rust source of truth for bootstrapping a GresIQ connection and validating that a managed database endpoint is reachable.

#What the bootstrap includes

• GresiqConfig for loading a managed Postgres target from environment variables
• explicit smbCloud environment handling for development, preview, and production
• branch metadata for project, branch, and region aware workloads
• TLS-aware tokio-postgres connection setup
• redacted connection-string output for logs and CLI diagnostics
• a health-check query that returns database name, user, and server version

#Environment variables

GresiqConfig::from_env() reads:

GRESIQ_PROJECT_SLUG
GRESIQ_HOST
GRESIQ_USERNAME
GRESIQ_PASSWORD
GRESIQ_BRANCH=main
GRESIQ_REGION=eu-north-1
GRESIQ_DATABASE=postgres
GRESIQ_PORT=5432
GRESIQ_SSL_MODE=require
GRESIQ_COMPUTE_TIER=autoscale
GRESIQ_APPLICATION_NAME=gresiq
GRESIQ_CONNECT_TIMEOUT_SECONDS=10
SMBCLOUD_ENVIRONMENT=development

#Example

use gresiq::GresiqConfig;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let config = GresiqConfig::from_env()?;
    let connection = config.connect().await?;
    let health_check = connection.health_check().await?;

    println!("{}", config.redacted_connection_string());
    println!("{}", health_check.server_version);

    Ok(())
}

#CLI bootstrap

Run the crate binary directly to validate a managed endpoint:

cargo run -p gresiq

The binary prints:

• branch and region summary
• selected compute tier
• redacted endpoint URL
• database health-check details

#Product direction

The current bootstrap focuses on connection modeling and operational correctness. The next logical layer for GresIQ is:

• branch lifecycle APIs for preview environments
• pooled or proxy-based serverless connection routing
• passwordless or ephemeral credentials
• metrics, query insights, and tenant-aware usage controls
• adapters for smbCloud CLI, Tauri, wasm, npm, and native SDKs
