Struct postgres_parser::nodes::Const

pub struct Const {

Const

Note: for varlena data types, we make a rule that a Const node's value must be in nonextended form (4byte header, no compression or external references). This ensures that the Const node is selfcontained and makes it more likely that equal() will see logically identical values as equal.

Fields

consttype: Oid

consttypmod: i32

constcollid: Oid

constlen: i32

constvalue: Datum

constisnull: bool

constbyval: bool

location: i32

Trait Implementations

impl Debug for Const

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Const

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

Deserialize this value from the given Serde deserializer.
