Trait for PostgreSQL native enum types that can be used as dyn objects

Required Methods

fn enum_type_name(&self) -> &'static str

Get the enum type name for PostgreSQL

fn as_enum(&self) -> &dyn PostgresEnum

fn variant_name(&self) -> &'static str

Get the string representation of this enum variant

fn into_boxed(&self) -> Box<dyn PostgresEnum>

Clone this enum as a boxed trait object

fn try_from_str(value: &str) -> Result<Self, DrizzleError>

where Self: Sized,

Try to create this enum from a string value

Trait Implementations

impl Clone for Box<dyn PostgresEnum>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for &dyn PostgresEnum

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

Formats the value using the given formatter.

impl Debug for Box<dyn PostgresEnum>

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

Formats the value using the given formatter.

impl PartialEq for &dyn PostgresEnum

fn eq(&self, other: &Self) -> 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 PartialEq for Box<dyn PostgresEnum>

fn eq(&self, other: &Self) -> 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.
