Struct ColumnRef 

pub struct ColumnRef {
    pub table: &'static str,
    pub name: &'static str,
    pub sql_type: &'static str,
    pub flags: ColumnFlags,
    pub dialect: ColumnDialect,
}

Column reference with full schema metadata.

Carries both the SQL rendering fields (table, name) and complete column metadata. SQL rendering code only uses the name fields and ignores extra metadata.

Fields

table: &'static str

name: &'static str

sql_type: &'static str

flags: ColumnFlags

dialect: ColumnDialect

Implementations

impl ColumnRef

pub const fn sql(table: &'static str, name: &'static str) -> Self

Creates a lightweight ColumnRef for SQL rendering only.

Only table and name are populated; metadata fields use empty defaults. Use a full struct literal for metadata-carrying refs.

pub const fn not_null(&self) -> bool

Returns true if this column is declared NOT NULL.

pub const fn primary_key(&self) -> bool

Returns true if this column participates in the primary key.

pub const fn unique(&self) -> bool

Returns true if this column has a UNIQUE constraint.

pub const fn has_default(&self) -> bool

Returns true if this column has a DEFAULT clause.

Trait Implementations

impl Clone for ColumnRef

fn clone(&self) -> ColumnRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ColumnRef

impl Debug for ColumnRef

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

Formats the value using the given formatter.

impl Eq for ColumnRef

impl From<&ColumnRef> for ColumnSqlRef

fn from(value: &ColumnRef) -> Self

Converts to this type from the input type.

impl From<ColumnRef> for ColumnSqlRef

fn from(value: ColumnRef) -> Self

Converts to this type from the input type.

impl<V: SQLParam> From<ColumnRef> for SQLChunk<'_, V>

fn from(value: ColumnRef) -> Self

Converts to this type from the input type.

impl PartialEq for ColumnRef

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for ColumnRef

impl<'a, V: SQLParam + 'a> ToSQL<'a, V> for ColumnRef

fn to_sql(&self) -> SQL<'a, V>

fn into_sql(self) -> SQL<'a, V>

where Self: Sized,

Consume self and return SQL without cloning. Default delegates to to_sql() (which clones). Types that own their SQL (like SQL and SQLExpr) override this to avoid the clone.
