Struct ForTemplateExpr

pub struct ForTemplateExpr {
    pub key_var: Option<Decorated<Ident>>,
    pub value_var: Decorated<Ident>,
    pub collection_expr: Expression,
    pub template: Template,
    pub strip: Strip,
    /* private fields */
}

A type representing the %{ for key_var, value_var in collection_expr } sub-expression and the template that follows after it within a ForDirective.

Fields

key_var: Option<Decorated<Ident>>

Optional iterator key variable identifier.

value_var: Decorated<Ident>

The iterator value variable identifier.

collection_expr: Expression

The expression that produces the list or object of elements to iterate over.

template: Template

The template that is included in the result string for each loop iteration.

strip: Strip

The whitespace strip behaviour to use on the template elements preceeding and following after the for expression.

Implementations

impl ForTemplateExpr

pub fn new( key_var: Option<impl Into<Decorated<Ident>>>, value_var: impl Into<Decorated<Ident>>, collection_expr: impl Into<Expression>, template: Template, ) -> ForTemplateExpr

Creates a new ForTemplateExpr from an optional key variable, value variable, collection expression and template.

pub fn preamble(&self) -> &RawString

Return a reference to the raw leading decor after the for’s opening {.

pub fn set_preamble(&mut self, preamble: impl Into<RawString>)

Set the raw leading decor after the for’s opening {.

Trait Implementations

impl Clone for ForTemplateExpr

fn clone(&self) -> ForTemplateExpr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ForTemplateExpr

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

Formats the value using the given formatter.

impl PartialEq for ForTemplateExpr

fn eq(&self, other: &ForTemplateExpr) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
