Struct PgEnumType 

pub struct PgEnumType { /* private fields */ }

PostgreSQL enum type metadata with ordered variants.

Implementations

impl PgEnumType

pub const fn new(name: PgEnumName) -> Self

Creates enum type metadata from a name.

pub fn with_schema(self, schema: PgSchemaName) -> Self

Adds schema qualification.

pub fn with_variants( self, variants: Vec<PgEnumVariant>, ) -> Result<Self, PgEnumError>

Replaces the ordered variant list.

Errors

Returns PgEnumError::DuplicateVariant when a label appears more than once.

pub fn push_variant( &mut self, variant: PgEnumVariant, ) -> Result<(), PgEnumError>

Appends a variant while preserving order.

Errors

Returns PgEnumError::DuplicateVariant when the label already exists.

pub const fn schema(&self) -> Option<&PgSchemaName>

Returns the optional schema name.

pub const fn name(&self) -> &PgEnumName

Returns the enum type name.

pub fn variants(&self) -> &[PgEnumVariant]

Returns ordered variants.

Trait Implementations

impl Clone for PgEnumType

fn clone(&self) -> PgEnumType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PgEnumType

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

Formats the value using the given formatter.

impl Display for PgEnumType

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

Formats the value using the given formatter.

impl Hash for PgEnumType

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 PgEnumType

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

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

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