Struct Cast 

pub struct Cast {
    pub this: Expression,
    pub to: DataType,
    pub trailing_comments: Vec<String>,
    pub double_colon_syntax: bool,
    pub format: Option<Box<Expression>>,
    pub default: Option<Box<Expression>>,
}

Represent a type cast expression.

Covers both the standard CAST(expr AS type) syntax and the PostgreSQL shorthand expr::type. Also used as the payload for TryCast and SafeCast variants. Supports optional FORMAT (BigQuery) and DEFAULT ON CONVERSION ERROR (Oracle) clauses.

Fields

this: Expression

The expression being cast.

to: DataType

The target data type.

trailing_comments: Vec<String>

double_colon_syntax: bool

Whether PostgreSQL :: syntax was used (true) vs CAST() function (false)

format: Option<Box<Expression>>

FORMAT clause for BigQuery: CAST(x AS STRING FORMAT ‘format_string’)

default: Option<Box<Expression>>

DEFAULT value ON CONVERSION ERROR (Oracle): CAST(x AS type DEFAULT val ON CONVERSION ERROR)

Trait Implementations

impl Clone for Cast

fn clone(&self) -> Cast

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Cast

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Cast

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Cast

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
