Trait Implementations

impl Clone for ContextInitializer

fn clone(&self) -> ContextInitializer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ContextInitializer for ContextInitializer

fn reserve_vars(&self) -> usize

For which size the builder should be preallocated

fn initialize(&self, _s: State, _source: Source) -> Context

Initialize default file context. Has default implementation, which calls populate. Prefer to always implement populate instead.

fn populate(&self, _for_file: Source, builder: &mut ContextBuilder)

For composability: extend builder. May panic if this initialization is not supported, and the context may only be created via initialize.

fn as_any(&self) -> &dyn Any

Allows upcasting from abstract to concrete context initializer. jrsonnet by itself doesn’t use this method, it is allowed for it to panic.

impl Trace for ContextInitializer

fn trace(&self, tracer: &mut Tracer<'_>)

Define how to visit values referred by this value.

fn is_type_tracked() -> bool

Whether this type should be tracked by the collector.
