Struct ROnExit

Source

pub(crate) struct ROnExit {
    pub expr: String,
    pub add: bool,
    pub after: bool,
}

Expand description

Parsed r_on_exit attribute for on.exit() cleanup code in R wrappers.

Two forms:

Short: r_on_exit = "expr" → ROnExit { expr, add: true, after: true }
Long: r_on_exit(expr = "...", add = false, after = false)

Defaults match R conventions for composable code: add = TRUE, after = TRUE.

impl ROnExit

Source

pub fn to_r_code(&self) -> String

add = FALSE (R default): on.exit(expr)
add = TRUE, after = TRUE: on.exit(expr, add = TRUE)
add = TRUE, after = FALSE: on.exit(expr, add = TRUE, after = FALSE)
