Struct SharedStorage

pub struct SharedStorage<Value: Clone> { /* private fields */ }

A shared storage.

Type Parameters

• Value - A value type.

Implementations

impl<Value: Clone + 'static> SharedStorage<Value>

pub fn new() -> Self

Creates a shared storage.

pub fn new_with_reader( reader: &mut dyn Read, value_deserializer: &mut ValueDeserializer<Value>, ) -> Result<Self, Error>

Creates a shared storage.

Arguments

• reader - A reader.
• value_deserializer - A deserializer for value objects.

Errors

• When it fails to read the memory.
