Struct Template 

pub struct Template { /* private fields */ }

A quoted HCL template: text, escaped when written, and expressions, interpolated as ${...}. Text can never become an interpolation, whatever it holds.

Implementations

impl Template

pub fn new() -> Template

An empty template.

pub fn text(text: impl Into<String>) -> Template

A template made of text only.

pub fn with_text(self, text: impl Into<String>) -> Template

The template with text appended.

pub fn with_expr(self, expr: Expression) -> Template

The template with expr interpolated at its end.

pub fn push_text(&mut self, text: impl Into<String>)

Appends text.

pub fn push_expr(&mut self, expr: Expression)

Appends an interpolation of expr.

pub fn append(&mut self, other: Template)

Appends other.

pub fn pieces(&self) -> impl Iterator<Item = Piece<'_>>

Its text and expressions, in order (for a caller that writes the template another way).

pub fn is_text(&self) -> bool

Whether it is plain text (no interpolation).

pub fn into_expression(self) -> Expression

The template as an expression: a plain string when it has no interpolation, the expression itself when it is one interpolation and nothing else ("${x}" is a form Terraform deprecates for x, which it converts where a string is wanted).

Trait Implementations

impl Clone for Template

fn clone(&self) -> Self

Returns a duplicate of the value.

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