Trait MemoryWriteHook 

pub trait MemoryWriteHook: Send + Sync {
    // Provided method
    fn before_write<'life0, 'life1, 'async_trait>(
        &'life0 self,
        _chunk: &'life1 NewMemoryChunk,
    ) -> Pin<Box<dyn Future<Output = Result<WriteDecision>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait { ... }
}

The hook providers consult before persisting a chunk.

Implementations must be cheap: this fires on every write through the memory subsystem. The daemon’s matcher-backed hook is O(rules) — that’s the v1 budget.

Provided Methods

fn before_write<'life0, 'life1, 'async_trait>( &'life0 self, _chunk: &'life1 NewMemoryChunk, ) -> Pin<Box<dyn Future<Output = Result<WriteDecision>> + Send + 'async_trait>>

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

Decide what to do with the chunk. Default impl returns Allow, which makes wiring a hook optional — most consumers can ignore this trait entirely.

Dyn Compatibility

This trait is dyn compatible.

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