Struct Relation 

pub struct Relation(/* private fields */);

A PostgreSQL relation name.

A relation is either a table or a view. Use this type when an operation accepts both tables and views (e.g., SELECT queries).

Implementations

impl Relation

pub const fn from_static_or_panic(input: &'static str) -> Self

Creates a new value from a static string.

Panics

Panics if the input is empty, exceeds MAX_LENGTH, or contains NUL bytes.

pub fn as_str(&self) -> &str

Returns the value as a string slice.

Trait Implementations

impl AsRef<str> for Relation

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Relation

fn clone(&self) -> Relation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Relation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Relation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Relation

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

Formats the value using the given formatter.

impl From<MaterializedView> for Relation

fn from(materialized_view: MaterializedView) -> Self

Converts to this type from the input type.

impl From<Table> for Relation

fn from(table: Table) -> Self

Converts to this type from the input type.

impl From<View> for Relation

fn from(view: View) -> Self

Converts to this type from the input type.

impl FromStr for Relation

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(input: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Ord for Relation

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

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

fn partial_cmp(&self, other: &Relation) -> 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 Serialize for Relation

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<String> for Relation

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from(value: String) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Relation
