Enum Def

pub enum Def {
    Scalar(ScalarDef),
    Struct(StructDef),
    TupleStruct(StructDef),
    Tuple(StructDef),
    Map(MapDef),
    List(ListDef),
    Enum(EnumDef),
}

The definition of a shape: is it more like a struct, a map, a list?

Variants

Scalar(ScalarDef)

Scalar — those don’t have a def, they’re not composed of other things. You can interact with them through ValueVTable.

e.g. u32, String, bool, SocketAddr, etc.

Struct(StructDef)

Struct with statically-known, named fields

e.g. struct Struct { field: u32 }

TupleStruct(StructDef)

Tuple-struct, with numbered fields

e.g. struct TupleStruct(u32, u32);

Tuple(StructDef)

Tuple, with numbered fields

e.g. (u32, u32);

Map(MapDef)

Map — keys are dynamic (and strings, sorry), values are homogeneous

e.g. Map<String, T>

List(ListDef)

Ordered list of heterogenous values, variable size

e.g. Vec<T>

Enum(EnumDef)

Enum with variants

e.g. enum Enum { Variant1, Variant2 }

Trait Implementations

impl Clone for Def

fn clone(&self) -> Def

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Def

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

Formats the value using the given formatter.

impl Hash for Def

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 PartialEq for Def

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