Struct fuchsia_inspect::types::Node

pub struct Node { /* private fields */ }

Inspect Node data type.

NOTE: do not rely on PartialEq implementation for true comparison. Instead leverage the reader.

NOTE: Operations on a Default value are no-ops.

Implementations

impl Node

pub fn clone_weak(&self) -> Node

Create a weak reference to the original node. All operations on a weak reference have identical semantics to the original node for as long as the original node is live. After that, all operations are no-ops.

pub fn create_child(&self, name: impl Into<StringReference>) -> Node

Add a child to this node.

pub fn record_child<F>(&self, name: impl Into<StringReference>, initialize: F)where F: FnOnce(&Node),

Creates and keeps track of a child with the given name.

pub fn atomic_update<F, R>(&self, update_fn: F) -> Rwhere F: FnOnce(&Node) -> R,

Takes a function to execute as under a single lock of the Inspect VMO. This function receives a reference to the Node where this is called.

pub fn create_lazy_child<F>( &self, name: impl Into<StringReference>, callback: F ) -> LazyNodewhere F: Fn() -> BoxFuture<'static, Result<Inspector, Error>> + Sync + Send + 'static,

Creates a new lazy child with the given name and callback. callback will be invoked each time the component’s Inspect is read.

pub fn record_lazy_child<F>( &self, name: impl Into<StringReference>, callback: F )where F: Fn() -> BoxFuture<'static, Result<Inspector, Error>> + Sync + Send + 'static,

Records a new lazy child with the given name and callback. callback will be invoked each time the component’s Inspect is read.

pub fn create_lazy_values<F>( &self, name: impl Into<StringReference>, callback: F ) -> LazyNodewhere F: Fn() -> BoxFuture<'static, Result<Inspector, Error>> + Sync + Send + 'static,

Trait Implementations

impl Debug for Node

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

Formats the value using the given formatter.

impl Default for Node

fn default() -> Node

Returns the “default value” for a type.

impl PartialEq for Node

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