Implementations

impl DSTORAGE_REQUEST_OPTIONS

Since DirectStorage is compiled with MSVC, we have to use it’s rules for C bitfields. MSVC will only pack fields of the same type in the same backing field.

struct DSTORAGE_REQUEST_OPTIONS {
     DSTORAGE_COMPRESSION_FORMAT CompressionFormat : 8;     // uint8_t  -> saved into A
     DSTORAGE_REQUEST_SOURCE_TYPE SourceType : 1;           // uint64_t -> packed together into B
     DSTORAGE_REQUEST_DESTINATION_TYPE DestinationType : 7; // uint64_t -> packed together into B
     UINT64 Reserved : 48;                                  // uint64_t -> packed together into B
};

// Resulting layout:
struct Storage {
     uint8_t A;
     uint8_t PADDING[7];
     uint64_t B;
}

pub fn CompressionFormat(&self) -> DSTORAGE_COMPRESSION_FORMAT

pub fn set_CompressionFormat(&mut self, value: DSTORAGE_COMPRESSION_FORMAT)

pub fn SourceType(&self) -> DSTORAGE_REQUEST_SOURCE_TYPE

pub fn set_SourceType(&mut self, value: DSTORAGE_REQUEST_SOURCE_TYPE)

Trait Implementations

impl Clone for DSTORAGE_REQUEST_OPTIONS

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DSTORAGE_REQUEST_OPTIONS

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

Formats the value using the given formatter.

impl Default for DSTORAGE_REQUEST_OPTIONS

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for DSTORAGE_REQUEST_OPTIONS

fn eq(&self, other: &Self) -> 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.
