Implementations

impl FdwOptions

pub fn new() -> FdwOptions

pub fn with(self, key: &str, value: &str) -> FdwOptions

pub fn get(&self, key: &str) -> Option<&str>

pub fn require(&self, key: &str) -> Result<&str, FdwError>

Fetch an option, returning a structured error when absent. Wrappers call this at scan time so callers get a clear message instead of a silent None.
