Struct CompilationScope 

pub struct CompilationScope {
    pub precompiler_data: Option<PrecompilerData>,
    pub once: bool,
    pub was_used: bool,
    /* private fields */
}

Fields

precompiler_data: Option<PrecompilerData>

optional precompiler data, only on the root scope

once: bool

If once is true, the scope can only be used for compilation once. E.g. for a REPL, this needs to be false, so that the scope can be reused

was_used: bool

If was_used is true, the scope has been used for compilation and should not be reused if once is true.

Implementations

impl CompilationScope

pub fn new(once: bool) -> CompilationScope
