Struct DependencyValues 

pub struct DependencyValues { /* private fields */ }

Typed dependency bag keyed by TypeId (UDF DependencyValues).

Reads use a shared RwLock read guard; writes take an exclusive guard. Clone is cheap (shared map).

Trait Implementations

impl Clone for DependencyValues

fn clone(&self) -> DependencyValues

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for DependencyValues

fn default() -> DependencyValues
