Enum SqlValue 

pub enum SqlValue {
    Null,
    Boolean(bool),
    Integer(i64),
    Real(f64),
    Text(String),
    Blob(Vec<u8>),
    Json(String),
}

A single SQL value. Boolean is carried as a distinct class (so a guest can express one and a strictly-typed engine could bind a native BOOL); libsql, being SQLite-family, maps it to 0/1.

Variants

Null

SQL NULL.

Boolean(bool)

A boolean (a native BOOL where the engine has one, else 0/1).

Integer(i64)

A 64-bit signed integer.

Real(f64)

A 64-bit float.

Text(String)

UTF-8 text.

Blob(Vec<u8>)

A byte string.

Json(String)

A JSON document (its JSON text) — the portable “JSON document” value, bound to each engine’s canonical document type: jsonb on Postgres (validated, canonical, operator- and index-capable), the binary JSON type on MySQL, text (json1) on SQLite. So a guest writes a jsonb/JSON column with no :: cast, AND the value type-unifies with such a column in COALESCE/comparison/||, not only on INSERT. Note Postgres jsonb validates on write (malformed JSON is rejected). Postgres’s raw-text json type is out of the portable model — use raw SQL with an explicit ::json cast for it. Read back as Text (the engines stringify JSON on the way out).
