struct kvm_stats_header - Header of per vm/vcpu binary statistics data. @flags: Some extra information for header, always 0 for now. @name_size: The size in bytes of the memory which contains statistics name string including trailing ‘\0’. The memory is allocated at the send of statistics descriptor. @num_desc: The number of statistics the vm or vcpu has. @id_offset: The offset of the vm/vcpu stats’ id string in the file pointed by vm/vcpu stats fd. @desc_offset: The offset of the vm/vcpu stats’ descriptor block in the file pointd by vm/vcpu stats fd. @data_offset: The offset of the vm/vcpu stats’ data block in the file pointed by vm/vcpu stats fd.

This is the header userspace needs to read from stats fd before any other readings. It is used by userspace to discover all the information about the vm/vcpu’s binary statistics. Userspace reads this header from the start of the vm/vcpu’s stats fd.

Trait Implementations

impl Clone for kvm_stats_header

fn clone(&self) -> kvm_stats_header

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for kvm_stats_header

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for kvm_stats_header

fn default() -> kvm_stats_header

Returns the “default value” for a type.

impl PartialEq for kvm_stats_header

fn eq(&self, other: &kvm_stats_header) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
