Expand description

Protocol used by user pagers to publish memory attribution statistics.

Variants§

SendPageRefaultCount

Sends a VMO containing a shared count of the number of page refaults of a pager. The shared count is a single atomic 64-bit unsigned integer.

Fields

§page_refaults_vmo: Vmo

§control_handle: PageRefaultSinkControlHandle

#[non_exhaustive]
_UnknownMethod

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

Fields

This variant is marked as non-exhaustive

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: PageRefaultSinkControlHandle

§method_type: MethodType
