Struct hcl::expr::Conditional

pub struct Conditional {
    pub cond_expr: Expression,
    pub true_expr: Expression,
    pub false_expr: Expression,
}

The conditional operator allows selecting from one of two expressions based on the outcome of a boolean expression.

Fields

cond_expr: Expression

A condition expression that evaluates to a boolean value.

true_expr: Expression

The expression returned by the conditional if the condition evaluates to true.

false_expr: Expression

The expression returned by the conditional if the condition evaluates to false.

Implementations

impl Conditional

pub fn new<C, T, F>(cond_expr: C, true_expr: T, false_expr: F) -> Conditionalwhere C: Into<Expression>, T: Into<Expression>, F: Into<Expression>,

Creates a new Conditional from a condition and two expressions for the branches of the conditional.

Trait Implementations

impl Clone for Conditional

fn clone(&self) -> Conditional

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Conditional

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Conditional

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Evaluate for Conditional

type Output = Value

The type that is returned by evaluate on success.

fn evaluate(&self, ctx: &Context<'_>) -> EvalResult<Self::Output>

Recursively evaluates all HCL templates and expressions in the implementing type using the variables and functions declared in the Context.

impl Format for Conditional

fn format<W>(&self, fmt: &mut Formatter<'_, W>) -> Result<()>where W: Write,

Formats a HCL structure using a formatter and writes the result to the provided writer.

fn format_vec<W>(&self, fmt: &mut Formatter<'_, W>) -> Result<Vec<u8>>where W: Write + AsMut<Vec<u8>>,

Formats a HCL structure using a formatter and returns the result as a Vec<u8>.

fn format_string<W>(&self, fmt: &mut Formatter<'_, W>) -> Result<String>where W: Write + AsMut<Vec<u8>>,

Formats a HCL structure using a formatter and returns the result as a String.

impl From<Conditional> for Conditional

fn from(value: Conditional) -> Self

Converts to this type from the input type.

impl From<Conditional> for Conditional

fn from(value: Conditional) -> Self

Converts to this type from the input type.

impl From<Conditional> for Expression

fn from(cond: Conditional) -> Self

Converts to this type from the input type.

impl<'de> IntoDeserializer<'de, Error> for Conditional

type Deserializer = MapAccessDeserializer<ConditionalAccess>

The type of the deserializer being converted into.

fn into_deserializer(self) -> Self::Deserializer

Convert this value into a deserializer.

impl PartialEq<Conditional> for Conditional

fn eq(&self, other: &Conditional) -> 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 Serialize for Conditional

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 Conditional

impl StructuralEq for Conditional

impl StructuralPartialEq for Conditional
