Struct ColumnNameRef 

pub struct ColumnNameRef(/* private fields */);

The name of a column or column alias.

Used in SELECT, INSERT, UPDATE SET, and RETURNING clauses.

Implementations

impl ColumnNameRef

pub const fn from_str(raw: &str) -> &Self

Transparently reinterprets the string slice as a strongly-typed ColumnNameRef

pub const fn from_static(raw: &'static str) -> &'static Self

Transparently reinterprets the static string slice as a strongly-typed ColumnNameRef

pub fn into_owned(self: Box<ColumnNameRef>) -> ColumnName

Converts a Box<ColumnNameRef> into a ColumnName without copying or allocating

pub const fn as_str(&self) -> &str

Provides access to the underlying value as a string slice.

impl Ord for ColumnNameRef

fn cmp(&self, other: &ColumnNameRef) -> Ordering

This method returns an Ordering between self and other.

impl PartialEq<&ColumnNameRef> for ColumnName

fn eq(&self, other: &&ColumnNameRef) -> 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.

fn eq(&self, other: &ColumnName) -> 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<ColumnName> for ColumnNameRef

fn eq(&self, other: &ColumnName) -> 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<ColumnNameRef> for ColumnName

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

fn eq(&self, other: &ColumnNameRef) -> 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.

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.
