Struct ReferencePath 

pub struct ReferencePath {
    pub root: BindingId,
    pub chain: Vec<PathElem>,
}

Fields

root: BindingId

chain: Vec<PathElem>

Implementations

impl ReferencePath

pub fn is_bare_local(&self) -> bool

A local itself, with no field or element step. Only such a path can’t change behind a guard’s back, through an alias or in a call.

pub fn root(root: BindingId) -> Self

pub fn is_prefix_of(&self, other: &ReferencePath) -> bool

Whether a write to self may change what other reads. A key step of other (o[key]) may name any field or element, so any written step matches it. A written key matches only itself, as in TypeScript: values[index] = 4 leaves values[0] narrowed.

pub fn render(&self) -> String

Trait Implementations

impl Clone for ReferencePath

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReferencePath

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

Formats the value using the given formatter.

impl Eq for ReferencePath

impl Hash for ReferencePath

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ReferencePath

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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for ReferencePath

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for ReferencePath

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.
