Expand description
Not all options are recognized by all implementations. For example, at time of writing, Fxfs ignores all options.
Fields§
§initial_size: Option<u64>
Byte count for the initial size of the volume. Some implementations might ignore this setting.
guid: Option<[u8; 16]>
Unique GUID for the volume. If unspecified, a GUID will be generated.
type_guid: Option<[u8; 16]>
Type GUID for the volume. If unspecified, an implementation default is chosen. Some implementations might not support arbitrary volume types.

Source§type Borrowed<'a> = &'a mut CreateOptions
type Borrowed<'a> = &'a mut CreateOptions
The Rust type to use for encoding. This is a particular
Encode<Self>
type cheaply obtainable from &mut Self::Owned
. There are three cases: Read moreSource§fn take_or_borrow<'a>(
value: &'a mut <Self as TypeMarker>::Owned,
) -> Self::Borrowed<'a>
fn take_or_borrow<'a>( value: &'a mut <Self as TypeMarker>::Owned, ) -> Self::Borrowed<'a>
Cheaply converts from
&mut Self::Owned
to Self::Borrowed
. For
HandleBased
types this is “take” (it returns an owned handle and
replaces value
with Handle::invalid
), and for all other types it is
“borrow” (just converts from one reference to another).Source§impl TypeMarker for CreateOptions

Source§type Owned = CreateOptions
type Owned = CreateOptions
The owned Rust type which this FIDL type decodes into.
Source§fn inline_align(_context: Context) -> usize
fn inline_align(_context: Context) -> usize
Returns the minimum required alignment of the inline portion of the
encoded object. It must be a (nonzero) power of two.
Source§fn inline_size(_context: Context) -> usize
fn inline_size(_context: Context) -> usize
Returns the size of the inline portion of the encoded object, including
padding for alignment. Must be a multiple of
inline_align

fn encode_is_copy() -> bool
Returns true if the memory layout of
Self::Owned
matches the FIDL wire
format and encoding requires no validation. When true, we can optimize
encoding arrays and vectors of Self::Owned
to a single memcpy. Read moreSource§fn decode_is_copy() -> bool
