Struct StructDef 

pub struct StructDef {
    pub name: StrId,
    pub parent: Option<TypeId>,
    pub fields: Vec<Field>,
    pub methods: Vec<Method>,
}

A struct (record) type.

Field slots are numbered across the parent chain: a struct’s field list begins with its parent’s fields, so a child instance can be used wherever the parent is expected. Methods are looked up by name by Inst::GetProp, the struct’s own first, then the parent’s.

Examples

use bytecode_lang::{Field, StrId, StructDef, ValType};

let point = StructDef {
    name: StrId(0),
    parent: None,
    fields: vec![Field { name: StrId(1), ty: ValType::F64 }, Field { name: StrId(2), ty: ValType::F64 }],
    methods: vec![],
};
assert_eq!(point.fields.len(), 2);

Fields

name: StrId

The type’s name.

parent: Option<TypeId>

The parent struct type, if any.

fields: Vec<Field>

All fields, the parent’s first.

methods: Vec<Method>

Methods declared by this type (not the parent’s).

Trait Implementations

impl Clone for StructDef

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StructDef

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

Formats the value using the given formatter.

impl Default for StructDef

fn default() -> Self

Returns the “default value” for a type.

impl Display for StructDef

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

impl Eq for StructDef

impl Hash for StructDef

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for StructDef

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for StructDef

fn eq(&self, other: &Self) -> bool

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for StructDef

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
