Struct ComponentSelector

pub struct ComponentSelector {
    pub moniker_segments: Option<Vec<StringSelector>>,
    /* private fields */
}

Specifies a pattern of component monikers which identify components being selected for.

Component selectors support wildcarding, which will glob a single “level” of a component moniker. eg: core/*/echo will match all echo instances running only in realms directly under core, but none nested further.

Component selectors also support a recursive wildcard, which will glob multiple “levels” of a component moniker. eg: core/** will match all component instances running under core/ and all descendants of it. Note that the wildcard does not select core itself. Clients that wish to choose a subtree including the root should pass two selectors, eg: core core/** The recursive wildcard is only allowed as the final segment of the selector.

Fields

moniker_segments: Option<Vec<StringSelector>>

Vector encoding the a pattern for monikers of components being selected for. These monikers are child-monikers relative to a “root” hierarchy that the archivist is aware of.

There must be at least one StringSelector provided, which specifies the component names that are matched by the current selector.

Trait Implementations

impl Clone for ComponentSelector

fn clone(&self) -> ComponentSelector

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ComponentSelector

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

Formats the value using the given formatter.

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

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 ComponentSelector

fn default() -> ComponentSelector

Returns the “default value” for a type.

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

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 ComponentSelector

fn eq(&self, other: &ComponentSelector) -> 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 ComponentSelector

type Owned = ComponentSelector

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 ComponentSelector

type Borrowed<'a> = &'a ComponentSelector

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.
