Struct IfExpression 

pub struct IfExpression { /* private fields */ }

Represents an if expression.

Implementations

impl IfExpression

pub fn new<E: Into<Expression>, E2: Into<Expression>, E3: Into<Expression>>( condition: E, result: E2, else_result: E3, ) -> Self

Creates a new if expression with the given condition, result, and else result.

pub fn with_tokens(self, tokens: IfExpressionTokens) -> Self

Attaches tokens to this if expression.

pub fn with_branch<E: Into<Expression>, E2: Into<Expression>>( self, condition: E, result: E2, ) -> Self

Adds an elseif branch to this if expression.

pub fn push_branch(&mut self, branch: ElseIfExpressionBranch)

Adds an elseif branch to this if expression.

pub fn set_tokens(&mut self, tokens: IfExpressionTokens)

Attaches tokens to this if expression.

pub fn get_tokens(&self) -> Option<&IfExpressionTokens>

Returns a reference to the tokens attached to this if expression, if any.

pub fn get_condition(&self) -> &Expression

Returns a reference to the condition of this if expression.

pub fn mutate_condition(&mut self) -> &mut Expression

Returns a mutable reference to the condition of this if expression.

pub fn get_result(&self) -> &Expression

Returns a reference to the result of this if expression (returned when condition is true).

pub fn mutate_result(&mut self) -> &mut Expression

Returns a mutable reference to the result of this if expression.

pub fn get_else_result(&self) -> &Expression

Returns a reference to the else result of this if expression.

pub fn mutate_else_result(&mut self) -> &mut Expression

Returns a mutable reference to the else result of this if expression.

pub fn has_elseif_branch(&self) -> bool

Returns whether this if expression has any elseif branches.

pub fn iter_branches(&self) -> impl Iterator<Item = &ElseIfExpressionBranch>

Returns an iterator over the elseif branches of this if expression.

pub fn clear_elseif_branches(&mut self)

Removes all elseif branches from this if expression.

pub fn retain_elseif_branches_mut( &mut self, filter: impl FnMut(&mut ElseIfExpressionBranch) -> bool, )

Retains only the elseif branches that satisfy the predicate.

pub fn remove_branch(&mut self, index: usize) -> Option<ElseIfExpressionBranch>

Removes an elseif branch at the specified index and returns it.

pub fn iter_mut_branches( &mut self, ) -> impl Iterator<Item = &mut ElseIfExpressionBranch>

Returns a mutable iterator over the elseif branches of this if expression.

pub fn mutate_first_token(&mut self) -> &mut Token

Returns a mutable reference to the first token for this if expression, creating it if missing.

pub fn mutate_last_token(&mut self) -> &mut Token

Returns a mutable reference to the last token for this if expression, creating it if missing.

pub fn clear_comments(&mut self)

Clears all comments from the tokens in this node.

pub fn clear_whitespaces(&mut self)

Clears all whitespaces information from the tokens in this node.

Trait Implementations

impl Clone for IfExpression

fn clone(&self) -> IfExpression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IfExpression

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

Formats the value using the given formatter.

impl From<IfExpression> for Expression

fn from(if_expression: IfExpression) -> Expression

Converts to this type from the input type.

impl PartialEq for IfExpression

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