Struct PgColumn 

pub struct PgColumn { /* private fields */ }

PostgreSQL column metadata.

Implementations

impl PgColumn

pub const fn new(name: PgColumnName, type_name: PgTypeName) -> Self

Creates column metadata from a name and type name.

pub fn with_built_in_type(name: PgColumnName, ty: PgBuiltInType) -> Self

Creates column metadata using a built-in PostgreSQL type.

pub const fn with_nullability(self, nullability: PgNullability) -> Self

Sets the nullability label.

pub fn with_default(self, default: PgColumnDefault) -> Self

Sets a default-expression label.

pub const fn with_generated(self, generated: PgGeneratedKind) -> Self

Sets the generated-column label.

pub const fn with_identity(self, identity: PgIdentityKind) -> Self

Sets the identity-column label.

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

Returns the column name.

pub const fn type_name(&self) -> &PgTypeName

Returns the type name.

pub const fn nullability(&self) -> PgNullability

Returns the nullability label.

pub const fn default(&self) -> Option<&PgColumnDefault>

Returns the optional default label.

pub const fn generated(&self) -> Option<PgGeneratedKind>

Returns the optional generated-column label.

pub const fn identity(&self) -> Option<PgIdentityKind>

Returns the optional identity-column label.

Trait Implementations

impl Clone for PgColumn

fn clone(&self) -> PgColumn

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PgColumn

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

Formats the value using the given formatter.

impl Hash for PgColumn

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 PgColumn

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

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

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