Struct voile::check::monad::TCS

pub struct TCS {
    pub env: Gamma,
    pub local_env: Gamma,
    pub gamma: Gamma,
    pub local_gamma: Gamma,
    pub meta_context: MetaContext<Val>,
}

Type-checking state.

Fields

env: Gamma

Global value context.

local_env: Gamma

Local value context.

gamma: Gamma

Global typing context.

local_gamma: Gamma

Local typing context.

meta_context: MetaContext<Val>

Meta variable context. Always global.

Methods

impl TCS

pub fn fresh_meta(&mut self) -> Val

Create a new valid but unsolved meta variable, used for generating fresh metas during elaboration.

pub fn local_type(&self, dbi: DBI) -> &ValInfo

pub fn glob_type(&self, index: GI) -> &ValInfo

pub fn local_val(&self, dbi: DBI) -> &ValInfo

pub fn glob_val(&self, index: GI) -> &ValInfo

pub fn local_is_type(&self, dbi: DBI) -> bool

pub fn glob_is_type(&self, index: GI) -> bool

pub fn pop_local(&mut self)

pub fn glob_len(&self) -> usize

pub fn local_len(&self) -> usize

impl TCS

So you can do some functional programming based on method call chains.

pub fn unify(self, a: &Val, b: &Val) -> TCM

fn unify_neutral(self, a: &Neutral, b: &Neutral) -> TCM

fn unify_closure(self, a: &Closure, b: &Closure) -> TCM

fn unify_case_split(self, a: &CaseSplit, b: &CaseSplit) -> TCM

pub(crate) fn unify_variants(
    self,
    kind: VarRec,
    subset: &Variants,
    superset: &Variants
) -> TCM

impl TCS

pub fn check_decls(self, decls: Vec<AbsDecl>) -> TCM

impl TCS

So you can do some functional programming based on method call chains.

pub fn evaluate(self, abs: Abs) -> (ValInfo, Self)

Should be invoked only during type-checking, produce uid-based terms (which can be further type-checked).

pub fn expand_global(self, expr: Val) -> (Val, TCS)

impl TCS

So you can do some functional programming based on method call chains.

pub fn check(self, expr: &Abs, expected_type: &Val) -> ValTCM

pub fn infer(self, value: &Abs) -> ValTCM

pub fn subtype(self, sub: &Val, sup: &Val) -> TCM

Trait Implementations

impl Default for TCS

fn default() -> TCS

Returns the "default value" for a type.

impl Clone for TCS

fn clone(&self) -> TCS

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TCS

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
