Struct ReadOnly 

Source 
pub struct ReadOnly;
Expand description

Marker type used to signify that a hardened buffer is read-only.

The sodium_mprotect API can be used to set a region of memory to be read-only, or totally inaccessible, to minimise the risk of sensitive data being leaked. In order to provide a type-safe system for interacting with this API, we attach a zero-sized MprotectStatus marker type to hardened buffers, signifying the current memory-protection status of the buffer.

This type indicates a buffer may only be read from, and not written to. Attempts to write to a buffer in this state will result in the process being terminated.
