Struct TypedValue 

pub struct TypedValue {
    pub value: Value,
    pub type_hint: Option<Type>,
}

A parameter value paired with an optional type hint.

Type hints let drivers pick the right wire format when the value alone is ambiguous (e.g. distinguishing INTEGER from BIGINT).

Example

use toasty_sql::TypedValue;

let tv = TypedValue {
    value: toasty_core::stmt::Value::Null,
    type_hint: None,
};
assert!(tv.type_hint.is_none());

Fields

value: Value

The parameter value.

type_hint: Option<Type>

An optional type hint for the value.
