Struct RLogical 

#[repr(transparent)]
pub struct RLogical(i32);

R’s logical element type (the contents of a LGLSXP vector).

In R, logical vectors are stored as int with possible values:

• 0 for FALSE
• 1 for TRUE
• NA_LOGICAL (typically INT_MIN) for NA

Important: R may also contain other non-zero values in logical vectors (e.g., from low-level code). Those should be interpreted as TRUE.

This type is repr(transparent) over i32 so any raw value is valid, avoiding UB when viewing LGLSXP data as a slice.

Tuple Fields

0: i32
