#[repr(u32)]pub enum BlockMode {
ReadWrite = 0,
ReadOnly = 1,
VolatileWrite = 2,

Variants§
ReadWrite = 0
Reads and writes are allowed.
ReadOnly = 1
Only reads are allowed.
VolatileWrite = 2
Writes are allowed, but are stored in memory, not to disk.

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
.Source§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 moreSource§fn decode_is_copy() -> bool

type Borrowed<'a> = BlockMode
The Rust type to use for encoding. This is a particular
Encode<Self>
type cheaply obtainable from &Self::Owned
. There are three cases: Read moreSource§fn borrow(
value: &<BlockMode as TypeMarker>::Owned,
) -> <BlockMode as ValueTypeMarker>::Borrowed<'_>

Cheaply converts from
