Struct veloren_common_state::plugin::memory_manager::EcsAccessManager

pub struct EcsAccessManager {
    ecs_pointer: AtomicPtr<EcsWorld<'static, 'static>>,
}

This structure wraps the ECS pointer to ensure safety

Fields

ecs_pointer: AtomicPtr<EcsWorld<'static, 'static>>

Implementations

impl EcsAccessManager

pub fn execute_with<T>( &self, world: &EcsWorld<'_, '_>, func: impl FnOnce() -> T, ) -> T

pub unsafe fn get(&self) -> Option<&EcsWorld<'_, '_>>

This unsafe function returns a reference to the Ecs World

Safety

This function is safe to use if it matches the following requirements

• The reference and subreferences like Entities, Components … aren’t leaked out the thread
• The reference and subreferences lifetime doesn’t exceed the source function lifetime
• Always safe when called from retrieve_action if you don’t pass a reference somewhere else
• All that ensure that the reference doesn’t exceed the execute_with function scope

Trait Implementations

fn default() -> Self

Returns the “default value” for a type.
