Struct Flags

Source
pub struct Flags {
    pub writable: bool,
    pub executable: bool,
    pub user_accessible: bool,
    pub cached: bool,
}
Expand description

Defines the permissions for a region of memory. Used both for abstract regions of memory (e.g. entries in a memory map) and as a architecture-common representation of paging structures.

The Add implementation “coalesces” two sets of Flags, giving a set of Flags that has the permissions of both of the sets. For example, if one region is writable and the other is not, the coalesced flags will be writable. By default, a region is considered to be cached, so coalesced flags will only be cached if both input regions can safely be cached.
