Enum Mode 

#[non_exhaustive]
pub enum Mode<'a> {
    Script,
    Module {
        name: &'a str,
    },
    Repl,
}

Compilation mode

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Script

Compile as script: return value is value of final statement or early return

Module

Compile as module: return value is a module of top-level bindings, or that of early return

Fields

name: &'a str

Repl

Compile in REPL mode:

• Return value is a module of top-level bindings, including private bindings (e.g. imports)
• Early return is disallowed at top level
• Value of final statement is bound to _

Trait Implementations

impl<'a> Clone for Mode<'a>

fn clone(&self) -> Mode<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> PartialEq for Mode<'a>

fn eq(&self, other: &Mode<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
