Struct x86_64_xsave::state_components::StateComponentSizing

pub struct StateComponentSizing {
    pub uncompacted_byte_offset: usize,
    pub size: usize,
    pub supported_in: SupportedIn,
    pub requires_alignment_if_compacted: bool,
}

This structure is not valid for state components 0 (x87 state) or 1 (SSE state).

Fields

uncompacted_byte_offset: usize

Byte offset from base address of XSaveArea if uncompacted.

size: usize

Size of state component in bytes; never zero if obtained via StateComponent.sizing(), SizingQueryableUserStateComponent.sizing(), SupervisorStateComponent.sizing() or StateComponentSizing::sizing().

supported_in: SupportedIn

Which register supports this state component?

requires_alignment_if_compacted: bool

If compacted, does this state component require alignment to 64 bytes?

• If true, this extended state component is located on the next 64-byte boundary following the preceding state component.
• If false, it is located immediately following the preceding state component.

Methods

impl StateComponentSizing

pub fn sizing(bit: u8) -> Option<StateComponentSizing>

Query size using CPUID of the state component for bit.

bit must be between 2 and 62 inclusive.
