[−][src]Struct tokio::sync::watch::Ref

pub struct Ref<'a, T> { /* fields omitted */ }

This is supported on feature="sync" only.

Returns a reference to the inner value

Outstanding borrows hold a read lock on the inner value. This means that long lived borrows could cause the produce half to block. It is recommended to keep the borrow as short lived as possible.
