Struct fidl_fuchsia_io::AdvisoryLockRequest

    pub range: Option<AdvisoryLockRange>,
    pub wait: Option<bool>,
    /* private fields */
}

Fields

type_: Option<AdvisoryLockType>

The type of lock to be acquired.

If this field is absent, the [AdvisoryLock] method will fail with ZX_ERR_INVALID_ARGS.

range: Option<AdvisoryLockRange>

The byte range within the file to be locked.

The range can extend beyond the end of the file but cannot extend beyond the beginning of the file.

If this field is absent, the range defaults to the entire file.

wait: Option<bool>

Whether the file should wait reply to the [AdvisoryLock] method until the requested lock can be acquired.

If this field is absent, the file will not wait.

Trait Implementations

impl Clone for AdvisoryLockRequest

fn clone(&self) -> AdvisoryLockRequest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AdvisoryLockRequest

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

Formats the value using the given formatter.

impl<D: ResourceDialect> Decode<AdvisoryLockRequest, D> for AdvisoryLockRequest

fn new_empty() -> Self

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_, D>, offset: usize, depth: Depth, ) -> Result<()>

Decodes an object of type T from the decoder’s buffers into self.

impl Default for AdvisoryLockRequest

fn default() -> AdvisoryLockRequest

Returns the “default value” for a type.

impl<D: ResourceDialect> Encode<AdvisoryLockRequest, D> for &AdvisoryLockRequest

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, offset: usize, depth: Depth, ) -> Result<()>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl PartialEq for AdvisoryLockRequest

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

impl TypeMarker for AdvisoryLockRequest

type Owned = AdvisoryLockRequest

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

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.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for AdvisoryLockRequest

type Borrowed<'a> = &'a AdvisoryLockRequest

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow(value: &<Self as TypeMarker>::Owned) -> Self::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.
