Struct ScopeBuilder 

pub struct ScopeBuilder { /* private fields */ }

Builder for creating scoped containers with pre-configured services.

Useful when you have a standard set of services to register per-scope.

Examples

use dependency_injector::{Container, ScopeBuilder};
use std::sync::atomic::{AtomicU64, Ordering};

static COUNTER: AtomicU64 = AtomicU64::new(0);

#[derive(Clone)]
struct RequestId(u64);

let root = Container::new();

let builder = ScopeBuilder::new()
    .with_transient(|| RequestId(COUNTER.fetch_add(1, Ordering::SeqCst)));

let scope1 = builder.build(&root);
let scope2 = builder.build(&root);

// Each scope gets its own services

pub fn with_lazy<T, F>(self, factory: F) -> Self

where T: Injectable, F: Fn() -> T + Send + Sync + Clone + 'static,

pub fn with_transient<T, F>(self, factory: F) -> Self

where T: Injectable, F: Fn() -> T + Send + Sync + Clone + 'static,
