ExecutorOptions contains the configuration options for executer clients

func (*ExecutorOptions) AddTemplateVar

func (e *ExecutorOptions) AddTemplateVar(input *contextargs.MetaInput, templateType templateTypes.ProtocolType, reqID string, key string, value interface{})

AddTemplateVar adds given var to template context with given template type as prefix this method is no-op if template is not multi protocol

func (*ExecutorOptions) AddTemplateVars

func (e *ExecutorOptions) AddTemplateVars(input *contextargs.MetaInput, reqType templateTypes.ProtocolType, reqID string, vars map[string]interface{})

AddTemplateVars adds vars to template context with given template type as prefix this method is no-op if template is not multi protocol

func (ExecutorOptions) Copy

func (e ExecutorOptions) Copy() ExecutorOptions

Copy returns a copy of the executeroptions structure

func (*ExecutorOptions) CreateTemplateCtxStore

func (e *ExecutorOptions) CreateTemplateCtxStore()

CreateTemplateCtxStore creates template context store (which contains templateCtx for every scan)

func (*ExecutorOptions) EncodeTemplate

func (e *ExecutorOptions) EncodeTemplate() string

func (eo *ExecutorOptions) RateLimitTake()

todo: centralizing components is not feasible with current clogged architecture a possible approach could be an internal event bus with pub-subs? This would be less invasive than reworking dep injection from scratch
