Trait ValueType

pub trait ValueType: Sized {
    // Required methods
    fn try_from(v: Value) -> Result<Self, ValueTypeErr>;
    fn type_name() -> String;
    fn array_type() -> ArrayType;

    // Provided methods
    fn unwrap(v: Value) -> Self { ... }
    fn expect(v: Value, msg: &str) -> Self { ... }
}

Required Methods

fn try_from(v: Value) -> Result<Self, ValueTypeErr>

fn type_name() -> String

fn array_type() -> ArrayType

fn column_type() -> ColumnType

Provided Methods

fn unwrap(v: Value) -> Self

fn expect(v: Value, msg: &str) -> Self

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
