Implementations

impl Expr

pub fn has_unresolved_modules(&self) -> bool

pub async fn resolve_modules<'a>( &'a self, resolvers: &'a Arc<[ModuleResolver]>, ) -> Result<Expr>

Resolve external modules referenced in the expression using the resolvers list. Each resolver will be tried in order, until one succeeds. If no resolver succeeds then an error will be returned.

impl Expr

pub fn new(kind: ExprKind, pos: SourcePosition) -> Self

pub fn fold<T, F: FnMut(T, &Self) -> T>(&self, init: T, f: &mut F) -> T

fold over self and all of self’s sub expressions

Trait Implementations

impl Clone for Expr

fn clone(&self) -> Expr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Expr

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

Formats the value using the given formatter.

impl Default for Expr

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Expr

fn deserialize<D>(de: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Expr

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

Formats the value using the given formatter.

impl FromStr for Expr

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for Expr

fn eq(&self, rhs: &Expr) -> 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 Expr

fn partial_cmp(&self, rhs: &Expr) -> 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.

impl PrettyDisplay for Expr

fn fmt_pretty_inner(&self, buf: &mut PrettyBuf) -> Result

Do the actual pretty print. This should not be called directly, it will be called by fmt_pretty when we know it can’t fit on a single line.

fn fmt_pretty(&self, buf: &mut PrettyBuf) -> Result

This is the user facing fmt method, it will first try to format the expression on a single line, and if that is impossible it will call the pretty printer.

fn to_string_pretty(&self, limit: usize) -> LPooled<String>

Pretty print to a pooled string

impl Serialize for Expr

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Expr
