Implementations

impl PgIndexFlags

pub const fn unique(self, value: bool) -> Self

Sets the unique flag.

pub const fn primary(self, value: bool) -> Self

Sets the primary-index flag.

pub const fn partial(self, value: bool) -> Self

Sets the partial-index flag.

pub const fn expression(self, value: bool) -> Self

Sets the expression-index flag.

pub const fn concurrent(self, value: bool) -> Self

Sets the concurrent-build flag.

pub const fn invalid(self, value: bool) -> Self

Sets the invalid-index flag.

pub const fn is_unique(self) -> bool

Returns true when the unique flag is set.

pub const fn is_primary(self) -> bool

Returns true when the primary-index flag is set.

pub const fn is_partial(self) -> bool

Returns true when the partial-index flag is set.

pub const fn is_expression(self) -> bool

Returns true when the expression-index flag is set.

pub const fn is_concurrent(self) -> bool

Returns true when the concurrent-build flag is set.

pub const fn is_invalid(self) -> bool

Returns true when the invalid-index flag is set.

Trait Implementations

impl Clone for PgIndexFlags

fn clone(&self) -> PgIndexFlags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PgIndexFlags

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

Formats the value using the given formatter.

impl Default for PgIndexFlags

fn default() -> PgIndexFlags

Returns the “default value” for a type.

impl Hash for PgIndexFlags

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 PgIndexFlags

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

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

fn partial_cmp(&self, other: &PgIndexFlags) -> 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.
