Value

Enum Value 

Source
#[non_exhaustive]
pub enum Value { Null, Bool(bool), Int(i64), Float(f64), String(String), Array(Vec<Self>), }
Expand description

SQL parameter values.

Variants (Non-exhaustive)§

This enum is marked as 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.
§

Null

SQL NULL value.

§

Bool(bool)

Boolean value (true/false).

§

Int(i64)

64-bit signed integer.

§

Float(f64)

64-bit floating point number.

§

String(String)

UTF-8 string value.

§

Array(Vec<Self>)

Array of values (for IN, BETWEEN operators).

Implementations§

Source§

impl Value

Source

pub fn from_json(json: &JsonValue) -> Option<Self>

Convert from miniserde JSON value.

§Example
use mik_sql::Value;
use miniserde::json::{Value as JsonValue, Number};

let json = JsonValue::String("hello".to_string());
assert_eq!(Value::from_json(&json), Some(Value::String("hello".to_string())));

let json = JsonValue::Number(Number::I64(42));
assert_eq!(Value::from_json(&json), Some(Value::Int(42)));
