Trait SystemCapability 

pub trait SystemCapability: Send + Sync {
    // Provided methods
    fn pre_init(&self, _sys: &SystemContext) -> Result<()> { ... }
    fn post_init<'life0, 'life1, 'async_trait>(
        &'life0 self,
        _sys: &'life1 SystemContext,
    ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
       where Self: 'async_trait,

             'life1: 'async_trait { ... }
}

System capability: receives runtime internals before init.

This trait is internal to toolkit and only used by gears with the “system” capability. Normal user gears don’t implement this.

Provided Methods

fn pre_init(&self, _sys: &SystemContext) -> Result<()>

Optional pre-init hook for system gears.

This runs BEFORE init() has completed for ALL gears, and only for system gears.

Default implementation is a no-op so most gears don’t need to implement it.

Errors

Returns an error if system wiring fails.

fn post_init<'life0, 'life1, 'async_trait>( &'life0 self, _sys: &'life1 SystemContext, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Optional post-init hook for system gears.

This runs AFTER init() has completed for ALL gears, and only for system gears.

Default implementation is a no-op so most gears don’t need to implement it.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
