Struct ConnectionConfig 

pub struct ConnectionConfig {
    pub database: String,
    pub user: String,
    pub password: Option<Zeroizing<String>>,
    pub params: HashMap<String, String>,
    pub connect_timeout: Option<Duration>,
    pub statement_timeout: Option<Duration>,
    pub keepalive_idle: Option<Duration>,
    pub application_name: Option<String>,
    pub extra_float_digits: Option<i32>,
}

Connection configuration

Stores connection parameters including database, credentials, and optional timeouts. Use ConnectionConfig::builder() for advanced configuration with timeouts and keepalive.

Fields

database: String

Database name

user: String

Username

password: Option<Zeroizing<String>>

Password (optional, zeroed on drop for security)

params: HashMap<String, String>

Additional connection parameters

connect_timeout: Option<Duration>

TCP connection timeout (default: 10 seconds)

statement_timeout: Option<Duration>

Query statement timeout

keepalive_idle: Option<Duration>

TCP keepalive idle interval (default: 5 minutes)

application_name: Option<String>

Application name for Postgres logs (default: “fraiseql-wire”)

extra_float_digits: Option<i32>

Postgres extra_float_digits setting

Implementations

impl ConnectionConfig

pub fn new(database: impl Into<String>, user: impl Into<String>) -> Self

Create new configuration with defaults

Arguments

• database - Database name
• user - Username

Defaults

• connect_timeout: None
• statement_timeout: None
• keepalive_idle: None
• application_name: None
• extra_float_digits: None

For configured timeouts and keepalive, use builder() instead.

pub fn builder( database: impl Into<String>, user: impl Into<String>, ) -> ConnectionConfigBuilder

Create a builder for advanced configuration

Use this to configure timeouts, keepalive, and application name.

Examples

use fraiseql_wire::connection::ConnectionConfig;
use std::time::Duration;
let config = ConnectionConfig::builder("mydb", "user")
    .connect_timeout(Duration::from_secs(10))
    .statement_timeout(Duration::from_secs(30))
    .build();

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

Set password (automatically zeroed on drop)

pub fn param(self, key: impl Into<String>, value: impl Into<String>) -> Self

Add connection parameter
