Macro sp_runtime::bounded_btree_map

macro_rules! bounded_btree_map {
    ($ ( $key:expr => $value:expr ),* $(,)?) => { ... };
}

Re-export bounded_vec and bounded_btree_map macros only when std is enabled. Build a bounded btree-map from the given literals.

The type of the outcome must be known.

Will not handle any errors and just panic if the given literals cannot fit in the corresponding bounded vec type. Thus, this is only suitable for testing and non-consensus code.
