Enum proof_of_sql::base::database::LiteralValue

#[non_exhaustive]
pub enum LiteralValue<S: Scalar> {
    Boolean(bool),

Represents a literal value.

Note: The types here should correspond to native SQL database types. See <https://ignite.apache.org/docs/latest/sql-reference/data-types> for a description of the native types used by Apache Ignite.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Boolean(bool)

Boolean literals

SmallInt(i16)

i16 literals

Int(i32)

i32 literals

BigInt(i64)

i64 literals

VarChar((String, S))

String literals

• the first element maps to the str value.
• the second element maps to the str hash (see crate::base::scalar::Scalar).

Int128(i128)

i128 literals

Decimal75(Precision, i8, S)

Decimal literals with a max width of 252 bits

• the backing store maps to the type crate::base::scalar::Curve25519Scalar

Scalar(S)

Scalar literals

TimeStampTZ(PoSQLTimeUnit, PoSQLTimeZone, i64)

TimeStamp defined over a unit (s, ms, ns, etc) and timezone with backing store mapped to i64, which is time units since unix epoch

Implementations

impl<S: Scalar> LiteralValue<S>

pub fn column_type(&self) -> ColumnType

Provides the column type associated with the column

Trait Implementations

impl<S: Clone + Scalar> Clone for LiteralValue<S>

fn clone(&self) -> LiteralValue<S>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<S: Debug + Scalar> Debug for LiteralValue<S>

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

Formats the value using the given formatter.

impl<'de, S> Deserialize<'de> for LiteralValue<S>

where S: Deserialize<'de> + Scalar,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<S: PartialEq + Scalar> PartialEq for LiteralValue<S>

fn eq(&self, other: &LiteralValue<S>) -> 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<S> Serialize for LiteralValue<S>

where S: Serialize + Scalar,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<S: Eq + Scalar> Eq for LiteralValue<S>

impl<S: Scalar> StructuralPartialEq for LiteralValue<S>
