Type Alias ColumnId

pub(crate) type ColumnId = ColumnId;

Aliased Type

struct ColumnId(/* private fields */);

Implementations

impl ColumnId

pub const fn get_id(&self) -> i32

pub const fn next(self) -> ColumnId

Returns the subsequent column id.

pub fn apply_delta_if_not_row_id(&mut self, delta: i32)

impl ColumnId

pub const fn new(column_id: i32) -> ColumnId

pub const fn placeholder() -> ColumnId

Sometimes the id field is filled later, we use this value for better debugging.

pub const fn first_user_column() -> ColumnId

Trait Implementations

impl Clone for ColumnId

fn clone(&self) -> ColumnId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnId

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

Formats the value using the given formatter.

impl Display for ColumnId

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

Formats the value using the given formatter.

impl From<&i32> for ColumnId

fn from(column_id: &i32) -> ColumnId

Converts to this type from the input type.

impl From<i32> for ColumnId

fn from(column_id: i32) -> ColumnId

Converts to this type from the input type.

impl Hash for ColumnId

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 Ord for ColumnId

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ColumnId

fn eq(&self, other: &ColumnId) -> 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 PartialOrd for ColumnId

fn partial_cmp(&self, other: &ColumnId) -> Option<Ordering>

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.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl PkColumn for ColumnId

fn is(&self, column: &ColumnCatalog) -> bool

impl Copy for ColumnId

impl Eq for ColumnId
