Struct FieldSchema 

pub struct FieldSchema {
    pub name: &'static str,
    pub ty: BuiltinType,
}

One field of a builtin struct.

Error and MapEntry are structs the language builds rather than a module declares, and a program reads them the ordinary way, by field. The runtime has always built both — a Value::Struct with the fields below — so what this adds is the half the checker was missing: what the runtime builds, written down where the checker can read it.

This is FieldSchema in the builtin vocabulary, carrying a BuiltinType because a builtin struct may be generic: MapEntry<K, V>’s two fields are its two type parameters.

Fields

name: &'static str

The label Cove source writes to read the field, such as message.

ty: BuiltinType

The field’s type.

Trait Implementations

impl Clone for FieldSchema

fn clone(&self) -> FieldSchema

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for FieldSchema

impl Debug for FieldSchema

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

Formats the value using the given formatter.

impl Eq for FieldSchema

impl PartialEq for FieldSchema

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