Struct eyros::Setup

pub struct Setup<S, U> where
    S: RandomAccess<Error = Error>,
    U: Fn(&str) -> Result<S, Error>,  {
    pub open_store: U,
    pub fields: SetupFields,
}

Builder to configure and instantiate an eyros database.

The Setup builder lets you create a database with a more custom configuration:

use eyros::{DB,Setup};
use random_access_disk::RandomAccessDisk;
use std::path::PathBuf;

type P = ((f32,f32),(f32,f32));
type V = u32;

let mut db: DB<_,_,P,V> = Setup::new(storage)
  .branch_factor(5)
  .max_data_size(3_000)
  .base_size(1_000)
  .build()?;

fn storage(name: &str) -> Result<RandomAccessDisk,Error> {
  let mut p = PathBuf::from("/tmp/eyros-db/");
  p.push(name);
  Ok(RandomAccessDisk::builder(p).auto_sync(false).build()?)
}
