Enum LimitClause 

pub enum LimitClause {
    LimitOffset {
        limit: Option<Expr>,
        offset: Option<Offset>,
        limit_by: Vec<Expr>,
    },
    OffsetCommaLimit {
        offset: Expr,
        limit: Expr,
    },
}

Represents the different syntactic forms of LIMIT clauses.

Variants

LimitOffset

Standard SQL LIMIT syntax (optionally BY and OFFSET).

LIMIT <limit> [BY <expr>,<expr>,...] [OFFSET <offset>]

Fields

limit: Option<Expr>

LIMIT { <N> | ALL } expression.

offset: Option<Offset>

Optional OFFSET expression with optional ROW(S) keyword.

limit_by: Vec<Expr>

Optional BY { <expr>,... } list used by some dialects (ClickHouse).

OffsetCommaLimit

MySQL-specific syntax: LIMIT <offset>, <limit> (order reversed).

Fields

offset: Expr

The offset expression.

limit: Expr

The limit expression.

Trait Implementations

impl Clone for LimitClause

fn clone(&self) -> LimitClause

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LimitClause

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

Formats the value using the given formatter.

impl Display for LimitClause

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

Formats the value using the given formatter.

impl Hash for LimitClause

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 LimitClause

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

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

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

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 LimitClause

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

Visit this node with the provided Visitor.

impl VisitMut for LimitClause

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

Mutably visit this node with the provided VisitorMut.

impl Eq for LimitClause
