pub enum ExtendedAttributeValue {
Bytes(Vec<u8>),
Buffer(Vmo),
}
Expand description
The value type for an extended attribute. If the value is less than 32768 bytes, then it is included inline. Values larger than this size are written into a vmo buffer.

§type Borrowed<'a> = &'a mut ExtendedAttributeValue
type Borrowed<'a> = &'a mut ExtendedAttributeValue
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 ExtendedAttributeValue

§type Owned = ExtendedAttributeValue
type Owned = ExtendedAttributeValue
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
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 more§fn decode_is_copy() -> bool
