Struct erg_compiler::context::Context

pub struct Context { /* private fields */ }

Represents the context of the current scope

Recursive functions/methods are highlighted with the prefix rec_, as performance may be significantly degraded.

Implementations

impl Context

pub fn new_main_module() -> Self

impl Context

pub fn sort_types<'a>(
    &self,
    types: impl Iterator<Item = &'a Type>
) -> Vec<&'a Type>

Perform types linearization. TODO: Current implementation may be very inefficient.

C3 linearization requires prior knowledge of inter-type dependencies, and cannot be used for Erg structural subtype linearization

Algorithm:

[Int, Str, Nat, Never, Obj, Str!, Module]
=> [], [Int, Str, Nat, Never, Obj, Str!, Module]
=> [[Int]], [Str, Nat, Never, Obj, Str!, Module]
=> [[Int], [Str]], [Nat, Never, Obj, Str!, Module]
=> ...
=> [[Int, Nat, Never, Obj]], [Str, Str!], [Module]]
=> [[Never, Nat, Int, Obj], [Str!, Str], [Module]]
=> [Never, Nat, Int, Obj, Str!, Str, Module]
=> [Never, Nat, Int, Str!, Str, Module, Obj]
