Struct LetVar 

pub struct LetVar { /* private fields */ }

Builds a LET $var = <expr> statement for session-scoped variables. The variable is available in subsequent queries within the same session.

LetVar::new("limit", 10u32).to_surrealql();      // LET $limit = 10;
LetVar::new("ts", Raw("time::now()")).to_surrealql(); // LET $ts = time::now();

Implementations

pub fn literal<V: SurrealQL>(name: impl Into<String>, value: V) -> Self

Create a LET $name = <literal> statement.

pub fn to_surrealql(&self) -> String

pub fn to_surrealql_with_params(&self) -> (String, BTreeMap<String, Value>)

Render with $param placeholders (the LET value becomes a $param).
