folly::bind::ext

Implements standard storage semantics for folly::bind. This is used (with some additional constraints & tweaks) by async_closure captures. It can also be used for other single‐use data structurs ‐‐ this makes it easy to simultaneously define the types for, and construct, tuples, named tuples, structs, etc. Some examples of this are given in Bind.md.

Types

Name

Description

The binding flags for a bound argument.

bind_to_storage_policy

Policy that maps a binding to the storage type used to hold its value.

Metadata for a single bound argument: its binding type plus binding flags.

A bound‐args list tagged with the identifier string Str.

A binding identifier tag, such as "x"_id or the self‐reference tag.

Base class for any type modeling a list of bound args with modifiers.

merge_update_args

Concatenates several like_args lists, mapping each bind_info_t through BindInfoFn.

named_bind_info_t

A bind_info_t extended with a compile‐time identifier Tag.

Placeholder tag meaning a binding carries no name tag.

A bound‐args list tagged with the self‐reference identifier.

Tag type marking the self‐reference identifier.

unsafe_move_args

Tag and factory for unsafely moving the contents of a like_args list.

Type Aliases

Name

Constness flag applied to a bound argument.

Functions

Name

Description

bind_as_argument

Variables

Name

Description

named_bind_info_tag_v
