Struct prql_compiler::ir::decl::Decl

pub struct Decl {
    pub declared_at: Option<usize>,
    pub kind: DeclKind,
    pub order: usize,
    pub annotations: Vec<Annotation>,
}

A struct containing information about a single declaration.

Fields

declared_at: Option<usize>

kind: DeclKind

order: usize

Some declarations (like relation columns) have an order to them. 0 means that the order is irrelevant.

annotations: Vec<Annotation>

Trait Implementations

impl Clone for Decl

fn clone(&self) -> Decl

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Decl

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

Formats the value using the given formatter.

impl Default for Decl

fn default() -> Decl

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Decl

fn deserialize<__D>( __deserializer: __D ) -> Result<Decl, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Decl

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

Formats the value using the given formatter.

impl From<DeclKind> for Decl

fn from(kind: DeclKind) -> Decl

Converts to this type from the input type.

impl PartialEq for Decl

fn eq(&self, other: &Decl) -> 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 Serialize for Decl

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
