Struct DatabaseConfig 

pub struct DatabaseConfig {
    pub url: String,
    pub max_connections: u32,
    pub min_connections: u32,
    pub connect_timeout: u64,
    pub idle_timeout: u64,
    pub max_lifetime: u64,
    pub test_before_acquire: bool,

    pub lock_timeout_ms: Option<u64>,
    pub slow_query_threshold_ms: u64,
    pub after_connect: Vec<String>,
}

Database connection configuration. Backend-agnostic — works for PostgreSQL, MySQL, MariaDB, SQLite.

Fields

url: String

max_connections: u32

min_connections: u32

connect_timeout: u64

idle_timeout: u64

max_lifetime: u64

Close connections older than this many seconds (lets the DB rebalance, frees server memory).

test_before_acquire: bool

Ping each connection before handing it out. Off by default: saves one round-trip per acquire; enable behind proxies or failover setups that kill idle connections silently.

statement_timeout_ms: Option<u64>

Postgres statement_timeout in milliseconds, set at connection startup. None = server default.

lock_timeout_ms: Option<u64>

Postgres lock_timeout in milliseconds, set at connection startup. None = server default.

slow_query_threshold_ms: u64

Queries slower than this (milliseconds) are logged at WARN (SQL text only, never bound values).

after_connect: Vec<String>

SQL statements executed on every new connection. Useful for strict mode, timezone, charset, search_path, etc.

Implementations

impl DatabaseConfig

pub fn redact_url(url: &str) -> String

pub fn from_url(url: impl Into<String>) -> Self

Build from a full connection URL. Examples: postgres://user:pass@localhost:5432/mydb mysql://user:pass@localhost:3306/mydb sqlite:///path/to/db.sqlite3

pub fn from_env() -> Result<Self, VarError>

Build from environment variable (defaults to DATABASE_URL).

pub fn from_env_var(var: &str) -> Result<Self, VarError>

pub fn backend(&self) -> BackendKind

Detect the backend kind from the URL scheme.
