[−][src]Macro common_macros::hash_map
Macro to crate a HashMap
with a number of key-value pairs in it.
There is an alternate syntax, which allows insertion into an existing
map (and still uses const_expr_count!
to call map.reserve()
with).
Examples
use common_macros::hash_map; let is_fun_map = hash_map!{ "joke" => true, "cat" => true, };
use std::collections::HashMap; use common_macros::hash_map; fn setup_map() -> HashMap<u8,u8> { HashMap::new() } let mut map = hash_map!(with setup_map(); insert { 12 => 13, 13 => 56 }); hash_map!(with &mut map; insert { 44 => 45, 48 => 112, 1 => 4 });
