DbValue

Enum DbValue

#[non_exhaustive]pub enum DbValue {
    Null,
    Bool(bool),
    I64(i64),
    U64(u64),
    F64(f64),
    String(String),
    Bytes(Vec<u8>),
}

Expand description

A scalar parameter accepted by the controlled V1 database API.

SQL parameters are never included in framework logs or errors.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Null

Bool(bool)

I64(i64)

U64(u64)

F64(f64)

String(String)

Bytes(Vec<u8>)
