Struct ColumnRef 

pub struct ColumnRef {
    pub table: String,
    pub column: String,
    pub index: usize,
}

Reference to a column in a table.

Fields

table: String

Table name (or alias).

column: String

Column name.

index: usize

Column index in the table schema.

Implementations

impl ColumnRef

pub fn new( table: impl Into<String>, column: impl Into<String>, index: usize, ) -> Self

Creates a new column reference.

pub fn normalized_name(&self) -> String

Returns the normalized name (table.column).

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 Hash for ColumnRef

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 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.
