RbProc

Swift

public struct RbProc: RbObjectConvertible

A Ruby Proc.

Use this to create a Ruby Proc from a symbol or any Ruby object supporting to_proc.

This is most useful when passing a block to a method:

// Ruby: mapped = names.map(&:downcase)
let mapped = names.call("map", block: RbProc(RbSymbol("downcase")))

Use RbObject.init(blockCall:) to create a Ruby Proc from a Swift closure.

If you want to pass Swift code to a method as a block then just call RbObjectAccess.call(_:args:kwArgs:blockRetention:blockCall:) directly, no need for either RbProc or RbObject.


        init(object: any RbObjectConvertible)

Initialize from something that can be turned into a Ruby object.

Swift

public init(object: any RbObjectConvertible)


        init?(RbObject)

Try to initialize from a Ruby object.

Succeeds if the object can be used as a Proc (has to_proc).

Swift

public init?(_ value: RbObject)


        var rubyObject: RbObject

A Ruby object for the Proc

Swift

public var rubyObject: RbObject { get }
