Struct IfStatement 

pub struct IfStatement {
    pub if_block: ConditionalStatementBlock,
    pub elseif_blocks: Vec<ConditionalStatementBlock>,
    pub else_block: Option<ConditionalStatementBlock>,
    pub end_token: Option<AttachedToken>,
}

An IF statement.

Example (BigQuery or Snowflake):

IF TRUE THEN
    SELECT 1;
    SELECT 2;
ELSEIF TRUE THEN
    SELECT 3;
ELSE
    SELECT 4;
END IF

BigQuery Snowflake

Example (MSSQL):

IF 1=1 SELECT 1 ELSE SELECT 2

Fields

if_block: ConditionalStatementBlock

elseif_blocks: Vec<ConditionalStatementBlock>

Additional ELSEIF blocks.

else_block: Option<ConditionalStatementBlock>

Optional ELSE block.

end_token: Option<AttachedToken>

Optional trailing END token for the IF statement.

Trait Implementations

impl Clone for IfStatement

fn clone(&self) -> IfStatement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IfStatement

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

Formats the value using the given formatter.

impl Display for IfStatement

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

Formats the value using the given formatter.

impl From<IfStatement> for Statement

fn from(i: IfStatement) -> Self

Converts to this type from the input type.

impl Hash for IfStatement

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for IfStatement

fn cmp(&self, other: &IfStatement) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for IfStatement

fn eq(&self, other: &IfStatement) -> 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 PartialOrd for IfStatement

fn partial_cmp(&self, other: &IfStatement) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Spanned for IfStatement

fn span(&self) -> Span

Return the Span (the minimum and maximum Location) for this AST node, by recursively combining the spans of its children.

impl Visit for IfStatement

fn visit<V: Visitor>(&self, visitor: &mut V) -> ControlFlow<V::Break>

Visit this node with the provided Visitor.

impl VisitMut for IfStatement

fn visit<V: VisitorMut>(&mut self, visitor: &mut V) -> ControlFlow<V::Break>

Mutably visit this node with the provided VisitorMut.

impl Eq for IfStatement

impl StructuralPartialEq for IfStatement
