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".
