Trait Implementations

impl AsColumnType for PgLegacyChar

fn as_column_type() -> ColumnType

The SQL column type of this Rust type

impl Clone for PgLegacyChar

fn clone(&self) -> PgLegacyChar

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, E> DatumType<'a, E> for PgLegacyChar

fn nullable() -> bool

Whether this Rust type can represent NULL values

fn fallible() -> bool

Whether this Rust type can represent errors

fn try_from_result( res: Result<Datum<'a>, E>, ) -> Result<Self, Result<Datum<'a>, E>>

Try to convert a Result whose Ok variant is a Datum into this native Rust type (Self). If it fails the error variant will contain the original result.

fn into_result(self, _temp_storage: &'a RowArena) -> Result<Datum<'a>, E>

Convert this Rust type into a Result containing a Datum, or an error

impl Debug for PgLegacyChar

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

Formats the value using the given formatter.

impl Hash for PgLegacyChar

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 PgLegacyChar

fn cmp(&self, other: &PgLegacyChar) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for PgLegacyChar

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

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