Enum rusqlite::types::Value

pub enum Value {
    Null,
    Integer(i64),
    Real(f64),
    Text(String),
    Blob(Vec<u8>),
}

Owning dynamic type value. Value’s type is typically dictated by SQLite (not by the caller).

See ValueRef for a non-owning dynamic type value.

Variants

Null

The value is a NULL value.

Integer(i64)

The value is a signed integer.

Real(f64)

The value is a floating point number.

Text(String)

The value is a text string.

Blob(Vec<u8>)

The value is a blob of data
