Enum hcl::structure::TemplateExpr

pub enum TemplateExpr {
    QuotedString(String),
    Heredoc(Heredoc),
}

A template expression embeds a program written in the template sub-language as an expression.

This type wraps the raw template string representation. Refer to the documentation of the template module if you need to parse and further evaluate the raw template.

Variants

QuotedString(String)

A quoted template expression is delimited by quote characters (") and defines a template as a single-line expression with escape characters. The raw template string may contain escape sequences.

Heredoc(Heredoc)

A heredoc template expression is introduced by a << sequence and defines a template via a multi-line sequence terminated by a user-chosen delimiter. The raw template string in the heredoc may contain escape sequences.
