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

Errors

Returns DrizzleError::ConversionError when value is not a valid variant name for this enum.

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.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
