Struct hcl::template::Interpolation

pub struct Interpolation {
    pub expr: Expression,
    pub strip: StripMode,
}

An interpolation sequence evaluates an expression (written in the expression sub-language), converts the result to a string value, and replaces itself with the resulting string.

Fields

expr: Expression

The interpolated expression.

strip: StripMode

The whitespace strip mode to use on the template elements preceeding and following after this interpolation sequence.

Implementations

impl Interpolation

pub fn new<T>(expr: T) -> Interpolationwhere
    T: Into<Expression>,

Creates a new expression Interpolation.

pub fn with_strip(self, strip: StripMode) -> Interpolation

Sets the whitespace strip mode to use on the template elements preceeding and following after this interpolation sequence and returns the modified Interpolation.

Trait Implementations

impl Clone for Interpolation

fn clone(&self) -> Interpolation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Interpolation

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

Formats the value using the given formatter.

impl Format for Interpolation

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<Interpolation> for Element

fn from(interpolation: Interpolation) -> Self

Converts to this type from the input type.

impl<T> From<T> for Interpolationwhere
    T: Into<Expression>,

fn from(expr: T) -> Self

Converts to this type from the input type.

impl PartialEq<Interpolation> for Interpolation

fn eq(&self, other: &Interpolation) -> 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.
