fn read(
&mut self,

max_bytes: usize,
) -> Result<Option<Vec<u8>>, Self::Error>;
fn write(
&mut self,

}Expand description
Storage must bound a read before allocating/fetching more than max_bytes.
Writes install immutable bytes at their ordinary blob address.

Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
