Struct hcl_edit::expr::Traversal

pub struct Traversal {
    pub expr: Expression,
    pub operators: Vec<Decorated<TraversalOperator>>,
    /* private fields */
}

Traverse an expression to access attributes, object keys or element indices.

Fields

expr: Expression

The expression that the access operator is applied to.

operators: Vec<Decorated<TraversalOperator>>

The traversal operators to apply to expr one of the other.

Implementations

impl Traversal

pub fn new( expr: Expression, operators: Vec<Decorated<TraversalOperator>> ) -> Traversal

Creates a new Traversal structure from an expression and traversal operators that should be applied to it.

Trait Implementations

impl Clone for Traversal

fn clone(&self) -> Traversal

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Traversal

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

Formats the value using the given formatter.

impl Decorate for Traversal

fn decor(&self) -> &Decor

Returns a reference to the object’s Decor.

fn decor_mut(&mut self) -> &mut Decor

Returns a mutable reference to the object’s Decor.

fn decorate(&mut self, decor: impl Into<Decor>)

Decorate the object with decor in-place.

fn decorated(self, decor: impl Into<Decor>) -> Selfwhere Self: Sized,

Decorate the object with decor and return the modified value.

impl From<Traversal> for Expression

fn from(value: Traversal) -> Self

Converts to this type from the input type.

impl PartialEq<Traversal> for Traversal

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Span for Traversal

fn span(&self) -> Option<Range<usize>>

Obtains the span information. This only returns Some if the value was emitted by the parser.

impl Eq for Traversal
