Enum binjs_meta::spec::TypeSpec

pub enum TypeSpec {
    Array {
        contents: Box<Type>,
        supports_empty: bool,
    },
    NamedType(NodeName),
    TypeSum(TypeSum),
    Boolean,
    String,
    Number,
    UnsignedLong,
    Offset,
    Void,
    IdentifierName,
    PropertyKey,
}

The contents of a type, typically that of a field.

Note that we generally use Type, to represent the fact that some fields accept null while others do not.

Variants

Array

An array of values of the same type.

Fields of Array

contents: Box<Type>

The type of values in the array.

supports_empty: bool

If true, the array may be empty.

NamedType(NodeName)

TypeSum(TypeSum)

Boolean

A boolean.

String

A string.

Number

A number, as per JavaScript specifications.

UnsignedLong

Offset

A number of bytes in the binary file.

This spec is used only internally, as a hidden field injected by deanonymization, to represent lazy fields.

Void

Nothing.

For the moment, this spec is used only internally.

IdentifierName

A string used to represent something bound in a scope (i.e. a variable, but not a property). At this level, we make no distinction between Identifier and IdentifierName.

Actually maps to a subset of IdentifierName in webidl.

PropertyKey

A key for a property. For the time being, we make no distinction between variants such as LiteralPropertyName and IdentifierName-as-property-keys.
