Struct BindingProfileModes 

pub struct BindingProfileModes {
    pub scope: BindingScopeMode,
    pub hygiene: HygieneMode,
}

The binding and hygiene modes selected for a language profile.

Parsed from profile options and consumed by the profile-modes form to configure how a profile’s surface binds names.

Fields

scope: BindingScopeMode

The binding scope mode.

hygiene: HygieneMode

The macro hygiene mode.

Implementations

impl BindingProfileModes

pub fn from_options(options: &[(Symbol, Expr)]) -> Result<Self>

Derives modes from profile option pairs, defaulting unset modes.

Recognizes scope/binding keys for BindingScopeMode and hygiene for HygieneMode; other keys are ignored. Errors on an unknown mode symbol.

Examples

use sim_kernel::{Expr, Symbol};
use sim_lib_binding::{BindingProfileModes, BindingScopeMode, HygieneMode};

let modes = BindingProfileModes::from_options(&[
    (Symbol::new("scope"), Expr::Symbol(Symbol::new("dynamic"))),
    (Symbol::new("hygiene"), Expr::Symbol(Symbol::new("explicit"))),
])
.unwrap();
assert_eq!(modes.scope, BindingScopeMode::Dynamic);
assert_eq!(modes.hygiene, HygieneMode::Explicit);

Trait Implementations

impl Clone for BindingProfileModes

fn clone(&self) -> BindingProfileModes

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BindingProfileModes

impl Debug for BindingProfileModes

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BindingProfileModes

fn default() -> Self

Returns the “default value” for a type.

impl Eq for BindingProfileModes

impl PartialEq for BindingProfileModes

fn eq(&self, other: &BindingProfileModes) -> 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.
