lode/types/json

:json / :jsonb — an arbitrary JSON document stored in a single column.

The Gleam-side representation is Value itself (the JSON tree). dump serializes it to a JSON-text VString; the postgres adapter sends that into a jsonb column verbatim (Postgres accepts a text param for jsonb), and reads it back as text which load re-parses. cast accepts either a JSON string or an already-structured Value.

pub fn json() -> type_.LodeType(value.Value)
