Struct VmaSnapshot 

Source 
pub struct VmaSnapshot {
    pub id: VmaId,
    pub range: VirtAddrRange,
    pub rights: MappingFlags,
    pub reported_rights: MappingFlags,
    pub max_rights: MappingFlags,

    pub source_offset: PageOffset,
    pub huge_page_advice: HugePageAdvice,
    pub lock_mode: VmaLockMode,
    /* private fields */
}
Expand description

Stable metadata copied out of the mutable legacy backend. A snapshot may safely cross a lock boundary or a sleeping page-cache operation.
