Enum PagerStatsSinkRequest 

pub enum PagerStatsSinkRequest {
    SendPagerStats {
        pager_stats_vmo: Vmo,
        control_handle: PagerStatsSinkControlHandle,
    },
    #[non_exhaustive]
    _UnknownMethod {
        ordinal: u64,
        control_handle: PagerStatsSinkControlHandle,
        method_type: MethodType,
    },
}

Protocol used by user pagers to publish memory attribution statistics.

Variants

SendPagerStats

Sends a VMO containing shared counts of page refaults and total page faults, both measured in pages supplied by the pager including readahead. The shared counts are stored as two canonical monotonic atomic 64-bit unsigned integers from the start of the VMO:

• Offset 0: page_refaults (pages supplied that had already been supplied before)
• Offset 8: page_faults (total pages supplied by the user pager)

Fields

pager_stats_vmo: Vmo

control_handle: PagerStatsSinkControlHandle

#[non_exhaustive]

_UnknownMethod

An interaction was received which does not match any known method.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

ordinal: u64

Ordinal of the method that was called.

control_handle: PagerStatsSinkControlHandle

method_type: MethodType
