Implementations

impl Expr

pub fn uses_shared(&self) -> bool

Check if this expression accesses shared state.

Returns true if this expression or any of its sub-expressions reference shared state via {shared.field} syntax.

Examples

use dampen_core::expr::{Expr, SharedFieldAccessExpr, FieldAccessExpr};

// Shared field access
let shared_expr = Expr::SharedFieldAccess(SharedFieldAccessExpr {
    path: vec!["theme".to_string()],
});
assert!(shared_expr.uses_shared());

// Regular field access
let regular_expr = Expr::FieldAccess(FieldAccessExpr {
    path: vec!["count".to_string()],
});
assert!(!regular_expr.uses_shared());

pub fn uses_model(&self) -> bool

Check if this expression accesses the local model.

Returns true if this expression or any of its sub-expressions reference local model fields via {field} syntax.

Trait Implementations

impl Clone for Expr

fn clone(&self) -> Expr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Expr

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Expr

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Expr

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

impl Serialize for Expr

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
