Struct SqlColumnRef 

pub struct SqlColumnRef { /* private fields */ }

SQL column reference metadata.

Implementations

impl SqlColumnRef

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

Creates an unqualified column reference.

pub const fn qualified(table: SqlTableName, name: SqlColumnName) -> Self

Creates a table-qualified column reference.

pub fn with_alias(self, alias: SqlColumnAlias) -> Self

Adds a column alias.

pub const fn table(&self) -> Option<&SqlTableName>

Returns the optional table qualifier.

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

Returns the column name.

pub const fn alias(&self) -> Option<&SqlColumnAlias>

Returns the optional alias.

Trait Implementations

impl Clone for SqlColumnRef

fn clone(&self) -> SqlColumnRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SqlColumnRef

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

Formats the value using the given formatter.

impl Display for SqlColumnRef

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

Formats the value using the given formatter.

impl Hash for SqlColumnRef

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 SqlColumnRef

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

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

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