Struct persy::OpenOptions

pub struct OpenOptions { /* fields omitted */ }

Options, flags, configs which can be used to configure how a persy database is opened.

use persy::{OpenOptions, Persy, PersyId, PRes, ValueMode};

// This function will only be called on database creation
fn init(persy: &Persy) -> PRes<()> {
    let mut tx = persy.begin()?;

    persy.create_segment(&mut tx, "data")?;
    persy.create_index::<u64, PersyId>(&mut tx, "index", ValueMode::REPLACE)?;

    let prepared = persy.prepare_commit(tx)?;
    persy.commit(prepared)?;

    println!("Segment and Index successfully created");
    Ok(())
}

let persy = OpenOptions::new().create(true).prepare_with(init).open("target/persy.db")?;
