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

The initial IF block containing the condition and statements.

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<(), Error>

Formats the value using the given formatter.

impl Display for IfStatement

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

Formats the value using the given formatter.

impl Eq for IfStatement

impl From<IfStatement> for Statement

fn from(i: IfStatement) -> Statement

Converts to this type from the input type.

impl Hash for IfStatement

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

where __H: Hasher,

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 StructuralPartialEq for IfStatement

impl Visit for IfStatement

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

where V: Visitor,

Visit this node with the provided Visitor.

impl VisitMut for IfStatement

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

where V: VisitorMut,

Mutably visit this node with the provided VisitorMut.
