Record any item implementing Serialize and DeserializeOwned.

Required Associated Types

type Settings: PrecisionSettings

Type of the settings used by the recorder.

type RecordArgs: Clone

Arguments used to record objects.

type RecordOutput

Record output type.

type LoadArgs

Arguments used to load recorded objects.

Required Methods

fn save_item<I: Serialize>( &self, item: I, args: Self::RecordArgs, ) -> Result<Self::RecordOutput, RecorderError>

Saves an item.

This method is used by record to save the item.

Arguments

• item - Item to save.
• args - Arguments to use to save the item.

Returns

The output of the save operation.

fn load_item<I>(&self, args: &mut Self::LoadArgs) -> Result<I, RecorderError>

where I: DeserializeOwned,

Loads an item.

This method is used by load to load the item.

Arguments

• args - Arguments to use to load the item.

Returns

The loaded item.

Provided Methods

fn record<R>( &self, record: R, args: Self::RecordArgs, ) -> Result<Self::RecordOutput, RecorderError>

where R: Record<B>,

Records an item.

Arguments

• record - The item to record.
• args - Arguments used to record the item.

Returns

The output of the recording.

fn load<R>( &self, args: Self::LoadArgs, device: &B::Device, ) -> Result<R, RecorderError>

where R: Record<B>,

Load an item from the given arguments.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
