Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Value

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Value

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

Formats the value using the given formatter.

impl From<&str> for Value

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<Expr> for Value

Convert an Expr into a Value for use in correlated subquery filters.

Example

use qail_core::ast::builders::col;

// WHERE session_id = parent_table.id
.eq("session_id", col("parent_table.id"))

fn from(expr: Expr) -> Self

Converts to this type from the input type.

impl<'a> From<Option<&'a str>> for Value

fn from(opt: Option<&'a str>) -> Self

Converts to this type from the input type.

impl From<Option<String>> for Value

fn from(opt: Option<String>) -> Self

Converts to this type from the input type.

impl From<Option<Uuid>> for Value

fn from(opt: Option<Uuid>) -> Self

Converts to this type from the input type.

impl From<Option<bool>> for Value

fn from(opt: Option<bool>) -> Self

Converts to this type from the input type.

impl From<Option<i32>> for Value

fn from(opt: Option<i32>) -> Self

Converts to this type from the input type.

impl From<Option<i64>> for Value

fn from(opt: Option<i64>) -> Self

Converts to this type from the input type.

impl From<String> for Value

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<Uuid> for Value

fn from(u: Uuid) -> Self

Converts to this type from the input type.

impl From<bool> for Value

fn from(b: bool) -> Self

Converts to this type from the input type.

impl From<f64> for Value

fn from(n: f64) -> Self

Converts to this type from the input type.

impl From<i32> for Value

fn from(n: i32) -> Self

Converts to this type from the input type.

impl From<i64> for Value

fn from(n: i64) -> Self

Converts to this type from the input type.

impl PartialEq for Value

fn eq(&self, other: &Value) -> 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 Value

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for Value
