Struct LetScope 

pub struct LetScope { /* private fields */ }

LET binding scope for an execution context.

Security (S-03)

Drop implementation clears and shrinks the bindings map to prevent sensitive data from lingering in freed memory.

Implementations

impl LetScope

pub fn evaluate( let_bindings: &[LetBinding], executor: &CalExecutor, store: &dyn CalStoreFacade, query: &CalQuery, warnings: &mut Vec<String>, ) -> Result<Self, CalError>

Evaluate all LET bindings in declaration order.

Limits

• S-06: Maximum 5 LET bindings per query.
• C2-04: Each binding evaluation is capped at 1000 grains.

pub fn resolve(&self, name: &str) -> Result<&LetValue, CalError>

Resolve a $name reference.

Returns CalError::UnboundParameter if the name is not in scope.

Trait Implementations

impl Debug for LetScope

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

Formats the value using the given formatter.

impl Drop for LetScope

S-03: Clear and shrink bindings on drop to prevent data lingering.

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
