Enum hcl::Expression

#[non_exhaustive]
pub enum Expression {
    Null,
    Bool(bool),
    Number(Number),
    String(String),
    Array(Vec<Expression>),
    Object(Object<ObjectKey, Expression>),
    Raw(RawExpression),
}

A type representing the expression sub-language is used within attribute definitions to specify values.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Null

Represents a null value.

Bool(bool)

Represents a boolean.

Number(Number)

Represents a number, either integer or float.

String(String)

Represents a string.

Array(Vec<Expression>)

Represents array.

Object(Object<ObjectKey, Expression>)

Represents an object.

Raw(RawExpression)

Represents a raw HCL expression. This includes any expression kind that does match any of the enum variants above. See RawExpression for more details.
