Struct fuchsia_inspect_contrib::graph::Metadata

source · 
pub struct Metadata<'a> { /* private fields */ }
Expand description

A metadata item used to initialize metadata key value pairs of nodes and edges.

Implementations§

source§

impl<'a> Metadata<'a>

source

pub fn new( key: impl Into<Cow<'a, str>>, value: impl Into<MetadataValue<'a>>, ) -> Self

Create a new metadata item with the given key and value.

source

pub fn nested( key: impl Into<Cow<'a, str>>, value: impl IntoIterator<Item = Metadata<'a>> + 'a, ) -> Self

source

pub fn track_events(self) -> Self

Require that changes to this metadata node must be tracked. To support tracking events about changes the graph must be configured to support tracking events. This is a no-op if called on a nested node. It only works on leaf properties.
