Base Memory trait

The base interface for all Memory types.

Required Methods§

Source

fn memory_variables(&self) -> Vec<&str>

Get memory variable names

Returns all variable keys stored in memory.

Source

fn load_memory_variables<'life0, 'life1, 'async_trait>( &'life0 self, inputs: &'life1 HashMap<String, String>, ) -> Pin<Box<dyn Future<Output = Result<HashMap<String, Value>, MemoryError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Load memory variables

§Arguments
  • inputs - Current input
§Returns

Memory variable dictionary

Source

fn save_context<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, inputs: &'life1 HashMap<String, String>, outputs: &'life2 HashMap<String, String>, ) -> Pin<Box<dyn Future<Output = Result<(), MemoryError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Save context

§Arguments
  • inputs - User input
  • outputs - System output
§Contract

缺失 input / output key 时返回 MemoryError::SaveError。 所有内置实现(Buffer / Window / Summary / SummaryBuffer)行为一致, 不做静默空串兜底。

Source

fn clear<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<(), MemoryError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Clear memory

Dyn Compatibility§

This trait is dyn compatible.

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