Required Methods

fn read( &self, read_kind: Val<B>, address: Address, bytes: u32, solver: &mut Solver<'_, B>, tag: bool, ) -> Result<Val<B>, ExecError>

fn write( &mut self, write_kind: Val<B>, address: Address, data: Val<B>, solver: &mut Solver<'_, B>, tag: Option<Val<B>>, ) -> Result<Val<B>, ExecError>

fn initial_value(&self, address: Address, bytes: u32) -> Option<B>

fn memory_kind(&self) -> &'static str

Return a static string denoting the ‘kind’ of memory this custom region is representing, e.g. “device” or “page_table”. This information is only used for display purposes, and has not semantic meaning.

fn clone_dyn(&self) -> Box<dyn Send + Sync + CustomRegion<B>>

Trait objects (dyn T) are in general not cloneable, so we require a method that allows us to implement clone ourselves for types containing Box<dyn T>. The implementation will nearly always be just Box::new(self.clone()).

Dyn Compatibility

This trait is dyn compatible.

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