Struct ViewId 

#[repr(transparent)]
pub struct ViewId(pub u32);

An identifier for a view, unique within a database. It is stored in the db as the primary key column of st_view.

Tuple Fields

0: u32

Implementations

impl ViewId

pub fn idx(self) -> usize

Convert self to a usize suitable for indexing into an array.

impl ViewId

pub const SENTINEL: Self

The sentinel value for this type. This will be initialized to a valid ID upon insertion into a system table as a primary key.

pub fn is_sentinel(self) -> bool

Check if this ID is the sentinel value.

Trait Implementations

impl Clone for ViewId

fn clone(&self) -> ViewId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ViewId

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

Formats the value using the given formatter.

impl Default for ViewId

fn default() -> ViewId

Returns the “default value” for a type.

impl Display for ViewId

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

Formats the value using the given formatter.

impl From<ViewId> for u32

fn from(value: ViewId) -> Self

Converts to this type from the input type.

impl From<i32> for ViewId

fn from(value: i32) -> Self

Converts to this type from the input type.

impl From<u32> for ViewId

fn from(value: u32) -> Self

Converts to this type from the input type.

impl From<usize> for ViewId

fn from(value: usize) -> Self

Converts to this type from the input type.

impl Hash for ViewId

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 Ord for ViewId

fn cmp(&self, other: &ViewId) -> 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 ViewId

fn eq(&self, other: &ViewId) -> 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 ViewId

fn partial_cmp(&self, other: &ViewId) -> 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.
