Enum Param 

#[non_exhaustive]
pub enum Param {
    Json(Value),
    Text(String),
    Path(Vec<String>),
    Numeric(String),
    Offset(i64),
}

A parameter, in the form tokio-postgres will bind it.

Variants (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.

Json(Value)

A JSON value, bound as jsonb.

Text(String)

Text, bound as text.

Path(Vec<String>)

A path, bound as text[].

Numeric(String)

A number, bound as numeric via its text form — Postgres parses it exactly, where a float would not.

Offset(i64)

A ledger offset.
