General Rules for canonical name mangling
|
|
|
|
* No spaces between any values
|
|
|
|
* normal declarations - pkg::name
|
|
* builtin names - just their normal name e.g. `i32` or `string`
|
|
* nested - pkg::parent1::parent2::name
|
|
* file private - pkg::[file_name]::name
|
|
* Example: `pkg::[file.odin]::Type`
|
|
* polymorphic procedure/type - pkg::foo:TYPE
|
|
* naming convention for parameters
|
|
* type
|
|
* $typeid_based_name
|
|
* $$constant_parameter
|
|
* Example: `foo::to_thing:proc(u64)->([]u8)`
|
|
* nested decl in polymorphic procedure - pkg::foo:TYPE::name
|
|
* anonymous procedures - pkg::foo::$anon[file.odin:123]
|
|
* 123 is the file offset in bytes
