folly::bind::ext::merge_update_args

Synopsis

Declared in <folly/lang/bind/Bind.h>

template<
    typename BindInfoFn,
    typename... Ts>
class merge_update_args
    : public like_args

This is the implementation base for the bind::args modifiers such as constant and const_ref.

Name	Description
`like_args`	Base class for any type modeling a list of bound args with modifiers.

Name	Description
`binding_list_t`	The concatenated binding list with each `bind_info_t` mapped by `BindInfoFn`.

Name	Description
`merge_update_args` [constructor]	Constructors
`unsafe_tuple_to_bind`	Move out the concatenated tuple of bound values.

Name	Description
`~merge_update_args` [destructor]	Protected destructor; the type is only used as a base class.

Name	Description
`args<Ts...>`
`capture`	`bind::capture()` and `bind::capture_indirect()` work much like other `folly::bind` modifiers. However, since they're primarily intended for `async_closure` arguments, you will practically only use them: - alone, for non-`co_cleanup` arguments; - with `bind::in_place()` or `bind::in_place_with()`, for `co_cleanup` arguments; - with `constant()`, for either.
`capture_const_ref`	Sugar for `capture{const_ref{...}}`, capturing a const reference.
`capture_indirect`	Binds an async-closure capture whose pointer-like value is dereferenced once to expose the underlying object.
`capture_mut_ref`	Sugar for `capture{mut_ref{...}}`, capturing a mutable reference.
`const_ref`	Binding modifier that binds a const reference to each argument.
`constant`	Binding modifier that makes each argument `const`.
`copy`	Binding modifier that passes its arguments as decay-copied prvalues.
`id_arg`	A bound-args list tagged with the identifier string `Str`.
`move`	Binding modifier that passes its arguments as rvalue references.
`mut`	Binding modifier that keeps each argument mutable.
`mut_ref`	Binding modifier that binds a mutable reference to each argument.
`self_id_arg`	A bound-args list tagged with the self-reference identifier.
