Struct PrimaryKeyConstraint 

pub struct PrimaryKeyConstraint {
    pub name: Option<Ident>,
    pub index_name: Option<Ident>,
    pub index_type: Option<IndexType>,
    pub columns: Vec<IndexColumn>,
    pub index_options: Vec<IndexOption>,
    pub characteristics: Option<ConstraintCharacteristics>,
}

MySQL definition for PRIMARY KEY constraints statements:

• [CONSTRAINT [<name>]] PRIMARY KEY [index_name] [index_type] (<columns>) <index_options>

Actually the specification have no [index_name] but the next query will complete successfully:

CREATE TABLE unspec_table (
  xid INT NOT NULL,
  CONSTRAINT p_name PRIMARY KEY index_name USING BTREE (xid)
);

where:

• index_type is USING {BTREE | HASH}
• index_options is {index_type | COMMENT 'string' | ... %currently unsupported stmts% } ...

Fields

name: Option<Ident>

Constraint name.

Can be not the same as index_name

index_name: Option<Ident>

Index name

index_type: Option<IndexType>

Optional USING of index type statement before columns.

columns: Vec<IndexColumn>

Identifiers of the columns that form the primary key.

index_options: Vec<IndexOption>

Optional index options such as USING.

characteristics: Option<ConstraintCharacteristics>

Optional characteristics like DEFERRABLE.

Trait Implementations

impl Clone for PrimaryKeyConstraint

fn clone(&self) -> PrimaryKeyConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrimaryKeyConstraint

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

Formats the value using the given formatter.

impl Display for PrimaryKeyConstraint

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

Formats the value using the given formatter.

impl Eq for PrimaryKeyConstraint

impl From<PrimaryKeyConstraint> for ColumnOption

fn from(c: PrimaryKeyConstraint) -> ColumnOption

Converts to this type from the input type.

impl From<PrimaryKeyConstraint> for TableConstraint

fn from(constraint: PrimaryKeyConstraint) -> TableConstraint

Converts to this type from the input type.

impl Hash for PrimaryKeyConstraint

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 PrimaryKeyConstraint

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

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

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

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 PrimaryKeyConstraint

impl Visit for PrimaryKeyConstraint

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 PrimaryKeyConstraint

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

where V: VisitorMut,

Mutably visit this node with the provided VisitorMut.
