Enum ColumnRef 

pub enum ColumnRef {
    Static(&'static str),
    Owned(String),
}

Column reference used in filters (static literals or owned names).

Variants

Static(&'static str)

Static column name known at compile time.

Owned(String)

Owned column name created at runtime.

Implementations

impl ColumnRef

pub const fn static_str(value: &'static str) -> Self

Builds a static column reference without allocation.

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 Debug for ColumnRef

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

Formats the value using the given formatter.

impl From<&String> for ColumnRef

fn from(value: &String) -> Self

Converts to this type from the input type.

impl From<&str> for ColumnRef

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<String> for ColumnRef

fn from(value: String) -> Self

Converts to this type from the input type.

impl PartialEq for ColumnRef

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