Struct arret_runtime::boxed::refs::Capture

#[repr(transparent)]
pub struct Capture<T: Boxed> { /* fields omitted */ }

[−] Expand description

Special marker ref for parameters that are explicitly captured

Capturing GC managed values is usually not allowed as the captured values become invisible to the garbage collector and will become invalid on the next collection cycle. This is intended for use by special runtime functions that expose their captured values to the collector via an internal mechanism.
