Implementations

impl FnType

pub fn scope_refs(&self, scope: &ModPath) -> FnType

pub fn unbind_tvars(&self)

pub fn constrain_known(&self)

pub fn reset_tvars(&self) -> Self

pub fn replace_tvars(&self, known: &FxHashMap<ArcStr, Type>) -> Self

pub fn replace_auto_constrained(&self) -> Self

replace automatically constrained type variables with their constraint type. This is only useful for making nicer display types in IDEs and shells.

pub fn has_unbound(&self) -> bool

pub fn bind_as(&self, t: &Type)

pub fn alias_tvars(&self, known: &mut FxHashMap<ArcStr, TVar>)

pub fn collect_tvars(&self, known: &mut FxHashMap<ArcStr, TVar>)

pub fn contains<C: Ctx, E: UserEvent>( &self, env: &Env<C, E>, t: &Self, ) -> Result<bool>

pub fn check_contains<C: Ctx, E: UserEvent>( &self, env: &Env<C, E>, other: &Self, ) -> Result<()>

pub fn sigmatch<C: Ctx, E: UserEvent>( &self, env: &Env<C, E>, other: &Self, ) -> Result<bool>

Return true if function signatures match. This is contains, but does not allow labeled argument subtyping.

pub fn check_sigmatch<C: Ctx, E: UserEvent>( &self, env: &Env<C, E>, other: &Self, ) -> Result<()>

pub fn map_argpos( &self, other: &Self, ) -> FxHashMap<ArcStr, (Option<usize>, Option<usize>)>

Trait Implementations

impl Clone for FnType

fn clone(&self) -> FnType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FnType

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

Formats the value using the given formatter.

impl Default for FnType

fn default() -> Self

Returns the “default value” for a type.

impl Display for FnType

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

Formats the value using the given formatter.

impl Ord for FnType

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for FnType

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for FnType

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
