Struct QuackConfig 

pub struct QuackConfig {
    pub enabled: bool,
    pub uri: String,
    pub token: Option<String>,
    pub allow_other_hostname: bool,
    pub read_only: bool,
}

Experimental DuckDB Quack remote protocol server.

Quack exposes the DuckDB SQL surface of the in-process database. Keep it disabled unless you intentionally want DuckDB clients to attach/query this process directly.

Fields

enabled: bool

Install/load the Quack extension and start quack_serve after datasets are registered.

uri: String

Quack URI to listen on. quack:localhost uses DuckDB’s default port 9494.

token: Option<String>

Optional explicit authentication token. If omitted, Quack generates one at startup and DataPress logs it once.

allow_other_hostname: bool

Allow binding a non-local hostname such as quack:0.0.0.0:9494. For external exposure, put a TLS-terminating reverse proxy in front.

read_only: bool

Install a read-only authorization macro for remote queries. Enabled by default to match DataPress’ read-oriented HTTP API.

Implementations

impl QuackConfig

pub fn validate_enabled(&self) -> Result<(), AppError>

Validate the enabled Quack configuration against DuckDB’s current safety rules. The extension treats only the literal localhost as local unless allow_other_hostname is set.
