    pub query: String,
    pub normalized: String,
    pub tables: Vec<String>,

Query context for query-related hooks

Fields

is_read_only: bool

hook_context: HookContext

Trait Implementations

impl Clone for QueryContext

fn clone(&self) -> QueryContext

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for QueryContext

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl RequestView for QueryContext

Available on crate feature wasm-plugins only.

fn query(&self) -> Option<&str>

SQL text of the query being processed, if this request carries a query. Returns None for non-SQL protocol messages (e.g. Terminate, Sync) or for contexts that don’t carry SQL.

fn is_read_only(&self) -> bool

Whether the query is a read-only operation (SELECT / SHOW / …). Defaults to false for safety — an implementation that cannot classify a query should leave the default.

fn database(&self) -> Option<&str>

Target database from the client’s startup message.

fn client_id(&self) -> Option<&str>

Stable client session identifier.

fn tenant_id(&self) -> Option<&str>

Tenant identifier, for multi-tenant deployments.

impl Serialize for QueryContext

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
