zip = "0.5.11"

A postgresql instance can be created using
PgEmbed::new(PgSettings, FetchSettings)

Examples

use pg_embed::postgres::{PgEmbed, PgSettings};
use pg_embed::fetch;
use pg_embed::fetch::{OperationSystem, Architecture, FetchSettings, PG_V13};
use std::time::Duration;

let pg_settings = PgSettings{
    /// where to store the postgresql executables
    executables_dir: "data/postgres".to_string(),
    /// where to store the postgresql database
    database_dir: "data/db".to_string(),
    port: 5432,
    user: "postgres".to_string(),
    password: "password".to_string(),
    /// if persistent is false clean up files and directories on drop, otherwise keep them
    persistent: false,
    start_timeout: Duration::from_secs(15),
};
let fetch_settings = FetchSettings{
    host: "https://repo1.maven.org".to_string(),
    operating_system: OperationSystem::Darwin,
    architecture: Architecture::Amd64,
    version: PG_V13
};
let mut pg_emb = PgEmbed::new(pg_settings, fetch_settings);

/// async block only to show that these methods need to be executed in an async context
async {

    /// Download, unpack, create password file and database
    pg_emb.setup().await;

    /// start postgresql database
    pg_emb.start_db().await;

};
    /// stop postgresql database
    pg_emb.stop_db();

Recent Breaking Changes

pg-embed follows semantic versioning, so breaking changes should only happen upon major version bumps. The only exception to this rule is breaking changes that happen due to implementation that was deemed to be a bug, security concerns, or it can be reasonably proved to affect no code. For the full details, see CHANGELOG.md.
