Available on crate feature database and non-WebAssembly only.

Defines possible filter value values.

Variants

String(String)

String variant.

Integer(i64)

Integer variant.

Int(i64)

Alias for Integer (for compatibility with test code)

Float(f64)

Float variant.

Boolean(bool)

Boolean variant.

Bool(bool)

Alias for Boolean (for compatibility with test code)

Null

Null variant.

Array(Vec<String>)

Array variant.

FieldRef(F)

Field reference for field-to-field comparisons (e.g., WHERE discount_price < total_price)

Expression(Expression)

Arithmetic expression (e.g., WHERE total != unit_price * quantity)

OuterRef(OuterRef)

Outer query reference for correlated subqueries (e.g., WHERE books.author_id = OuterRef(“authors.id”))

Implementations

impl FilterValue

pub fn string(value: impl ToString) -> FilterValue

Create a String variant from any value that can be converted to String

Accepts any type that implements ToString, including:

• String, &str
• Uuid (via Display)
• Numeric types (i64, u64, etc. via Display)
