Derive Macro trait_based_collection_macros::FromIterator

#[derive(FromIterator)]

This macro is used to derive the FromIterator a standard implementation for all the data structures that implement the Collection trait. This macro will automatically take into account the size of the iterator and create a new instance of the data structure with the appropriate capacity. This is useful for collections that have a fixed size (that implement the FixedSizeCollection trait) as it will prevent the collection from having to resize itself multiple times.

Panics

This macro will panic if the input could not be properly parsed using the syn crate.
