Struct pgrx_sql_entity_graph::RustSqlMapping

pub struct RustSqlMapping {
    pub rust: String,
    pub sql: String,
    pub id: TypeId,
}

A mapping from a Rust type to a SQL type, with a TypeId.

use pgrx_sql_entity_graph::RustSqlMapping;

let constructed = RustSqlMapping::of::<i32>(String::from("int"));
let raw = RustSqlMapping {
    rust: core::any::type_name::<i32>().to_string(),
    sql: String::from("int"),
    id: core::any::TypeId::of::<i32>(),
};

assert_eq!(constructed, raw);

Fields

id: TypeId

Implementations

impl RustSqlMapping

pub fn of<T: 'static>(sql: String) -> Self

Trait Implementations

impl Clone for RustSqlMapping

fn clone(&self) -> RustSqlMapping

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RustSqlMapping

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

Formats the value using the given formatter.

impl Hash for RustSqlMapping

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 RustSqlMapping

fn cmp(&self, other: &RustSqlMapping) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for RustSqlMapping

fn eq(&self, other: &RustSqlMapping) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for RustSqlMapping

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

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

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