Enum ColumnValue 

pub enum ColumnValue {
    Int(i64),
    Float(f64),
    Text(String),
    Bool(bool),
    Bytes(Vec<u8>),
    Null,
}

Available on crate feature rdbc only.

A type-erased value that can be bound to a database column.

Used by RDBC item writers to carry field values from item extractor closures to database parameter binding at write time. This enum allows storing values of different types in a single collection without requiring static type dispatch.

Examples

use spring_batch_rs::item::rdbc::ColumnValue;

let v: ColumnValue = 42i32.into();
assert!(matches!(v, ColumnValue::Int(42)));

let v: ColumnValue = None::<i32>.into();
assert!(matches!(v, ColumnValue::Null));

Variants

Int(i64)

Signed integer (covers i32, i64).

Float(f64)

Floating-point number (covers f32, f64).

Text(String)

UTF-8 text (covers &str, String).

Bool(bool)

Boolean value.

Bytes(Vec<u8>)

Raw bytes.

Null

SQL NULL — produced by Option::None.
