Trait magnus::scan_args::ScanArgsBlock
source · pub trait ScanArgsBlock: ScanArgsBlock { }Expand description
Trait implemented for types that can be retrieved as a block argument by
scan_args.
This trait is implemented for Proc and Option<Proc>.
() also implements this trait as a placeholder for when no block argument
is required, although Ruby will still allow a block to be passed, it will
just ignore it (as is standard for all Ruby methods).
