Struct ConditionalStatementBlock 

pub struct ConditionalStatementBlock {
    pub start_token: AttachedToken,
    pub condition: Option<Expr>,
    pub then_token: Option<AttachedToken>,
    pub conditional_statements: ConditionalStatements,
}

A block within a Statement::Case or Statement::If or Statement::While-like statement

Example 1:

WHEN EXISTS(SELECT 1) THEN SELECT 1;

Example 2:

IF TRUE THEN SELECT 1; SELECT 2;

Example 3:

ELSE SELECT 1; SELECT 2;

Example 4:

WHILE @@FETCH_STATUS = 0
BEGIN
   FETCH NEXT FROM c1 INTO @var1, @var2;
END

Fields

start_token: AttachedToken

Token representing the start of the block (e.g., WHEN/IF/WHILE).

condition: Option<Expr>

Optional condition expression for the block.

then_token: Option<AttachedToken>

Optional token for the THEN keyword.

conditional_statements: ConditionalStatements

The statements contained in this conditional block.

Implementations

impl ConditionalStatementBlock

pub fn statements(&self) -> &Vec<Statement>

Get the statements in this conditional block.

Trait Implementations

impl Clone for ConditionalStatementBlock

fn clone(&self) -> ConditionalStatementBlock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConditionalStatementBlock

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

Formats the value using the given formatter.

impl Display for ConditionalStatementBlock

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

Formats the value using the given formatter.

impl Hash for ConditionalStatementBlock

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 ConditionalStatementBlock

fn cmp(&self, other: &ConditionalStatementBlock) -> 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 ConditionalStatementBlock

fn eq(&self, other: &ConditionalStatementBlock) -> 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 ConditionalStatementBlock

fn partial_cmp(&self, other: &ConditionalStatementBlock) -> 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 ConditionalStatementBlock

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 ConditionalStatementBlock

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

Visit this node with the provided Visitor.

impl VisitMut for ConditionalStatementBlock

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

Mutably visit this node with the provided VisitorMut.

impl Eq for ConditionalStatementBlock

impl StructuralPartialEq for ConditionalStatementBlock
