[#bsl-deque-0c-push_front-07] = xref:bsl.adoc[bsl]::xref:bsl/deque-0c.adoc[deque]::push_front :relfileprefix: ../../ :mrdocs: Prepend to the front of this deque the specified move‐insertable `value`. `value` is left in a valid but unspecified state. If an exception is thrown (other than by the move constructor of a non‐copy‐insertable `value_type`), this method has no effect. This method requires that the (template parameter) `VALUE_TYPE` be `move‐insertable` into this deque (see {Requirements on `VALUE_TYPE`}). == Synopsis Declared in `<bslstl_deque.h>` [source,cpp,subs="verbatim,replacements,macros,-callouts"] ---- void push_front(xref:BloombergLP/bslmf/MovableRef.adoc[BloombergLP::bslmf::MovableRef<value_type>] value); ---- [.small]#Created with https://www.mrdocs.com[MrDocs]#
