Struct ArrayAccess 

pub struct ArrayAccess { /* private fields */ }

Borrowed argument positions shared by analysis, evaluation and reconstruction.

Implementations

impl ArrayAccess

pub fn from_dispatch( dispatch: FunctionDispatch, arguments: usize, is_bare_null: impl Fn(usize) -> bool, ) -> Option<Result<Self, SQLError>>

Legacy slice plans use a bare NULL node for omitted syntax; typed and computed NULLs remain supplied expressions. Their original source SQL was not persisted.

pub fn validate_dimensions(self) -> Result<(), SQLError>

pub const fn slice_bounds(self) -> Option<ArraySliceBounds>

pub const fn bound_count(self) -> usize

pub fn is_omitted(self, argument: usize) -> bool

pub fn evaluation_order(self) -> impl Iterator<Item = usize>

Execution visits all upper bounds, then all lower bounds. Analysis retains written lower/upper order instead.

Trait Implementations

fn clone(&self) -> Self

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

Performs copy-assignment from source.

impl Copy for ArrayAccess

impl Debug for ArrayAccess

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

Formats the value using the given formatter.
