Struct Column

pub struct Column { /* private fields */ }

PostgreSQL table column.

Implementations

impl Column

pub fn new(table_name: impl ToString, column_name: impl ToString) -> Self

Create new table column, given the table name and column name.

Columns are ideally always fully qualified with the table name to avoid ambiguous errors.

pub fn name(column_name: impl ToString) -> Self

Create new table column, given the column name.

Not fully qualified, so use with care, or you’ll get ambiguous column error when joining, especially with common column names like “id”.

pub fn qualified(&self) -> bool

pub fn qualify(self, table_name: impl ToString) -> Self

pub fn unqualify(self) -> Self

pub fn as_value(self, value: impl ToValue) -> Self

Trait Implementations

impl Clone for Column

fn clone(&self) -> Column

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Column

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

Formats the value using the given formatter.

impl Display for Column

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

Formats the value using the given formatter.

impl PartialEq for Column

fn eq(&self, other: &Column) -> 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 ToColumn for Column

fn to_column(&self) -> Column

impl ToSql for Column

fn to_sql(&self) -> String

Convert self into a valid SQL entity.

impl ToValue for Column

fn to_value(&self) -> Value

Convert a Rust type to a Value. Data types have to have their own enum variant. Add one if your data type is missing (and submit a PR).
