Struct BopStruct 

pub struct BopStruct { /* private fields */ }

A user-defined struct value. Carries the module it was declared in plus the bare type name, so two modules that happen to declare struct Color { ... } independently produce distinct values even when they share a name. The module path is <root> for the top-level program and <builtin> for engine-registered builtins like RuntimeError; for user modules it’s the dot-joined use path ("std.math", "game.entity", …). Fields are stored in declaration order so iteration and Display stay stable.

Implementations

impl BopStruct

pub fn type_name(&self) -> &str

pub fn module_path(&self) -> &str

Module this struct type was declared in. Forms one half of the type’s identity — the other half is the bare Self::type_name.

pub fn fields(&self) -> &[(String, Value)]

pub fn field(&self, name: &str) -> Option<&Value>

Look up a field by name. None if no such field.

pub fn set_field(&mut self, name: &str, value: Value) -> bool

Replace the value of an existing field. Returns true if the field was present; false if the caller should raise a “no such field” error. The old value is dropped (firing its allocation tracking); no capacity change in the Vec.

Trait Implementations

impl Debug for BopStruct

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

Formats the value using the given formatter.
