Implementations

impl<'a> Metadata<'a>

pub fn new(slots: &'a mut [Option<(&'a str, &'a str)>]) -> Self

pub fn set_source(&mut self, source: Arc<dyn MetadataSource>)

Retain an existing shared source of Metadata without allocating per Query.

pub fn set_enabled(&mut self, enabled: bool)

Enable public Plugin Metadata for the current Server Block.

pub fn enabled(&self) -> bool

pub fn with_self_lookup( slots: &'a mut [Option<(&'a str, &'a str)>], handle: Option<&'a SelfLookupHandle>, ) -> Self

Construct fresh Metadata while retaining detached Self Lookup routing.

pub fn insert(&mut self, name: &'a str, value: &'a str) -> bool

Insert or replace a named value; returns false when no slot is free.

pub fn insert_inline(&mut self, name: &'static str, value: &str) -> bool

Copy a short value whose lifetime is shorter than the Query’s.

pub fn insert_copied(&mut self, name: &'static str, value: &str) -> bool

Copy a value from a temporary Plugin buffer without allocating.

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