Enum Element

pub enum Element {
    Literal(Spanned<String>),
    Interpolation(Interpolation),
    Directive(Directive),
}

An element of an HCL template.

Variants

Literal(Spanned<String>)

A literal sequence of characters to include in the resulting string.

Interpolation(Interpolation)

An interpolation sequence that evaluates an expression (written in the expression sub-language), and converts the result to a string value.

Directive(Directive)

An if or for directive that allows for conditional template evaluation.

Implementations

impl Element

pub fn is_literal(&self) -> bool

Returns true if the element represents a literal string.

pub fn as_literal(&self) -> Option<&Spanned<String>>

If the Element is a literal string, returns a reference to it, otherwise None.

pub fn is_interpolation(&self) -> bool

Returns true if the element represents an interpolation.

pub fn as_interpolation(&self) -> Option<&Interpolation>

If the Element is an interpolation, returns a reference to it, otherwise None.

pub fn is_directive(&self) -> bool

Returns true if the element represents a directive.

pub fn as_directive(&self) -> Option<&Directive>

If the Element is a directive, returns a reference to it, otherwise None.

Trait Implementations

impl Clone for Element

fn clone(&self) -> Element

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Element

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

Formats the value using the given formatter.

impl From<&str> for Element

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<Directive> for Element

fn from(value: Directive) -> Self

Converts to this type from the input type.

impl From<Interpolation> for Element

fn from(value: Interpolation) -> Self

Converts to this type from the input type.

impl From<Spanned<String>> for Element

fn from(value: Spanned<String>) -> Self

Converts to this type from the input type.

impl From<String> for Element

fn from(value: String) -> Self

Converts to this type from the input type.

impl PartialEq for Element

fn eq(&self, other: &Element) -> 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 Span for Element

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 Element

impl StructuralPartialEq for Element
