#[non_exhaustive]pub struct Let {
pub span: Span,
}
Expand description
The let
keyword.
Fields (Non-exhaustive)§
This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional
Struct { .. }
syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.span: Span
Associated span.
