Struct hcl::expr::UnaryOp

pub struct UnaryOp {
    pub operator: UnaryOperator,
    pub expr: Expression,
}

An operation that applies an operator to one expression.

Fields

operator: UnaryOperator

The unary operator to use on the expression.

expr: Expression

An expression that supports evaluation with the unary operator.

Implementations

impl UnaryOp

pub fn new<T>(operator: UnaryOperator, expr: T) -> UnaryOpwhere
    T: Into<Expression>,

Creates a new UnaryOp from an operator and an expression.

Trait Implementations

impl Clone for UnaryOp

fn clone(&self) -> UnaryOp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnaryOp

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for UnaryOp

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

Deserialize this value from the given Serde deserializer.

impl Evaluate for UnaryOp

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 UnaryOp

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.

impl From<UnaryOp> for Operation

fn from(op: UnaryOp) -> Self

Converts to this type from the input type.

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

type Deserializer = MapAccessDeserializer<UnaryOpAccess>

The type of the deserializer being converted into.

fn into_deserializer(self) -> Self::Deserializer

Convert this value into a deserializer.

impl PartialEq<UnaryOp> for UnaryOp

fn eq(&self, other: &UnaryOp) -> 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 UnaryOp

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 UnaryOp

impl StructuralEq for UnaryOp

impl StructuralPartialEq for UnaryOp
