Struct MutableMetadataHandle 

pub struct MutableMetadataHandle(/* private fields */);

A shared handle to a MutableMetadata.

This is a cheap-to-clone Arc<ArcSwap<MutableMetadata>>: all clones observe the same underlying value. See the module documentation for the write/read protocol.

Implementations

impl MutableMetadataHandle

pub fn load(&self) -> Guard<Arc<MutableMetadata>>

Load the value of the handle

pub fn load_full(&self) -> Arc<MutableMetadata>

Load the value of the handle, cloned into an owning Arc.

pub fn set_runtime_id(&self, runtime_id: String)

Set the runtime_id value

pub fn set_process_tags(&self, process_tags: String)

Set the process tags value

pub fn update<F>(&self, f: F)

where F: FnMut(MutableMetadata) -> MutableMetadata,

Update the handle value with the result of f.

Use this method to update multiple fields at once. Modify the supplied snapshot rather than replacing it with a previously loaded value. The closure may run more than once when another writer updates the handle concurrently.
