Struct IfDirective

pub struct IfDirective {
    pub if_expr: IfTemplateExpr,
    pub else_expr: Option<ElseTemplateExpr>,
    pub endif_expr: EndifTemplateExpr,
    /* private fields */
}

The template if directive is the template equivalent of the conditional expression, allowing selection of one of two sub-templates based on the condition result.

Fields

if_expr: IfTemplateExpr

The if sub-expression within the directive.

else_expr: Option<ElseTemplateExpr>

The else sub-expression within the directive. This is None if there is no else branch in which case the result string will be empty.

endif_expr: EndifTemplateExpr

The endif sub-expression within the directive.

Implementations

impl IfDirective

pub fn new( if_expr: IfTemplateExpr, else_expr: Option<ElseTemplateExpr>, endif_expr: EndifTemplateExpr, ) -> IfDirective

Creates a new IfDirective from the parts for the if, else and endif sub-expressions.

Trait Implementations

impl Clone for IfDirective

fn clone(&self) -> IfDirective

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IfDirective

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

Formats the value using the given formatter.

impl From<IfDirective> for Directive

fn from(value: IfDirective) -> Self

Converts to this type from the input type.

impl PartialEq for IfDirective

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

impl Span for IfDirective

fn span(&self) -> Option<Range<usize>>

Obtains the span information. This only returns Some if the value was emitted by the parser.
