Struct TableFunctionInfo 

pub struct TableFunctionInfo<V: VTab> { /* private fields */ }

An interface to store and retrieve data during the table function’s execution stage.

Implementations

impl<V: VTab> TableFunctionInfo<V>

pub fn bind_data(&self) -> &V::BindData

The bind data produced by VTab::bind for this call. Read-only.

pub fn init_data(&self) -> &V::InitData

The init data produced by VTab::init for this call. Shared across every worker thread executing this query, so any interior mutation must be synchronized.

pub fn local_init_data<T>(&self) -> Option<&T>

The data produced by VTabLocalInit::local_init for this worker thread, if the function registered a local-init callback. Returns None if no local-init callback was registered.

Safety

The caller must request the same T that was stored by the local-init callback; there is no runtime type check.

pub fn extra_info<T>(&self) -> Option<&T>

The registration-time “extra info”, if any — see BindInfo::extra_info.

Safety

The caller must request the same T that was stored at registration time; there is no runtime type check.
