Struct ColumnIdentity 

pub struct ColumnIdentity { /* private fields */ }

Structured SQL column identity. A qualifier is metadata, never a prefix encoded into the column name, so quoted names containing . remain intact.

Implementations

impl ColumnIdentity

pub fn unqualified(column: impl Into<String>) -> Self

pub fn qualified( qualifier: impl Into<String>, column: impl Into<String>, ) -> Self

pub fn qualifier(&self) -> Option<&str>

pub fn column(&self) -> &str

Trait Implementations

impl Clone for ColumnIdentity

fn clone(&self) -> ColumnIdentity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnIdentity

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

Formats the value using the given formatter.

impl Eq for ColumnIdentity

impl Hash for ColumnIdentity

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 ColumnIdentity

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

fn eq(&self, other: &ColumnIdentity) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for ColumnIdentity

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