Struct IndexConstraint 

pub struct IndexConstraint {
    pub display_as_key: bool,
    pub name: Option<Ident>,
    pub index_type: Option<IndexType>,
    pub columns: Vec<IndexColumn>,
    pub index_options: Vec<IndexOption>,
}

MySQLs index definition for index creation. Not present on ANSI so, for now, the usage is restricted to MySQL, as no other dialects that support this syntax were found.

{INDEX | KEY} [index_name] [index_type] (key_part,...) [index_option]...

Fields

display_as_key: bool

Whether this index starts with KEY (true) or INDEX (false), to maintain the same syntax.

name: Option<Ident>

Index name.

index_type: Option<IndexType>

Optional index type.

columns: Vec<IndexColumn>

Referred column identifier list.

index_options: Vec<IndexOption>

Optional index options such as USING; see IndexOption.

Trait Implementations

impl Clone for IndexConstraint

fn clone(&self) -> IndexConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IndexConstraint

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for IndexConstraint

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for IndexConstraint

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

Formats the value using the given formatter.

impl From<IndexConstraint> for TableConstraint

fn from(constraint: IndexConstraint) -> Self

Converts to this type from the input type.

impl Hash for IndexConstraint

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 IndexConstraint

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

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

fn partial_cmp(&self, other: &IndexConstraint) -> 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 Serialize for IndexConstraint

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Spanned for IndexConstraint

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 IndexConstraint

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

impl VisitMut for IndexConstraint

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