Enum fidl_fuchsia_pkg::BlobWriter
source · pub enum BlobWriter {
File(ClientEnd<FileMarker>),
Writer(ClientEnd<BlobWriterMarker>),
}
Expand description
Used to write a blob to the underlying storage.
Variants§
File(ClientEnd<FileMarker>)
To write a blob with file
:
- If the blob is uncompressed, use
fuchsia.io/File.Resize
to set the blob’s uncompressed size. - Use
fuchsia.io/File.Write
to write the blob’s contents from start to finish (seeks are not supported). A corrupt blob is indicated by aWrite()
(usually the final write), failing withZX_ERR_IO_DATA_INTEGRITY
.
Writer(ClientEnd<BlobWriterMarker>)
To write a blob with writer
, follow the instructions on the
fuchsia.fxfs.BlobWriter
protocol.

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

§type Owned = BlobWriter
type Owned = BlobWriter
The owned Rust type which this FIDL type decodes into.

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.

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
