Struct PropertySelector

pub struct PropertySelector {
    pub node_path: Vec<StringSelector>,
    pub target_properties: StringSelector,
}

A selector defining a set of nodes to match, and on those matched nodes a set of named properties to match.

Fields

node_path: Vec<StringSelector>

A vector of StringSelectors which serve as a pattern matcher for paths through a hierarchy of named nodes. Each entry in the vector is a selector for a single named node in a data hierarchy. The vector of selectors for named nodes, then, defines a selector on paths through the data hierarchy.

Node paths support wildcarding, which will glob a single level of a node hierarchy. eg: root/a/b//d will match all nodes named d which are below some child of node b. root/a/b/c will match all nodes below b which start with the character “c”.

target_properties: StringSelector

A StringSelector which serves as a pattern matcher for string-named properties on a node in a data hierarchy.

target_properties supports wildcarding, which will match against all properties on any node matched by node_path.

Trait Implementations

impl Clone for PropertySelector

fn clone(&self) -> PropertySelector

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PropertySelector

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

Formats the value using the given formatter.

impl<D> Decode<PropertySelector, D> for PropertySelector

where D: ResourceDialect,

fn new_empty() -> PropertySelector

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<(), Error>

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

impl<D> Encode<PropertySelector, D> for &PropertySelector

where D: ResourceDialect,

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

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

impl PartialEq for PropertySelector

fn eq(&self, other: &PropertySelector) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TypeMarker for PropertySelector

type Owned = PropertySelector

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 PropertySelector

type Borrowed<'a> = &'a PropertySelector

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: &<PropertySelector as TypeMarker>::Owned, ) -> <PropertySelector as ValueTypeMarker>::Borrowed<'_>

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