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 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 Eq for PrimaryKeyConstraint

impl StructuralPartialEq for PrimaryKeyConstraint
