Struct DeriveInputShapeSet

pub struct DeriveInputShapeSet {
    enum_values: DataShape,
    struct_values: DataShape,
    any: bool,
}

Receiver struct for shape validation. Shape validation allows a deriving type to declare that it only accepts - for example - named structs, or newtype enum variants.

#[ignore(any, struct_named, enum_newtype)]

Fields

enum_values: DataShape

struct_values: DataShape

any: bool

Trait Implementations

impl Clone for DeriveInputShapeSet

fn clone(&self) -> DeriveInputShapeSet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DeriveInputShapeSet

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

Formats the value using the given formatter.

impl Default for DeriveInputShapeSet

fn default() -> Self

Returns the “default value” for a type.

impl FromMeta for DeriveInputShapeSet

fn from_list(items: &[NestedMeta]) -> Result<Self>

Create an instance from a list of nested meta items.

fn from_nested_meta(item: &NestedMeta) -> Result<Self>

fn from_meta(item: &Meta) -> Result<Self>

Create an instance from a syn::Meta by dispatching to the format-appropriate trait function. This generally should not be overridden by implementers.

fn from_none() -> Option<Self>

When a field is omitted from a parent meta-item, from_none is used to attempt recovery before a missing field error is generated.

fn from_word() -> Result<Self>

Create an instance from the presence of the word in the attribute with no additional options specified.

fn from_value(value: &Lit) -> Result<Self>

Create an instance from a literal value of either foo = "bar" or foo("bar"). This dispatches to the appropriate method based on the type of literal encountered, and generally should not be overridden by implementers.

fn from_expr(expr: &Expr) -> Result<Self>

fn from_char(value: char) -> Result<Self>

Create an instance from a char literal in a value position.

fn from_string(value: &str) -> Result<Self>

Create an instance from a string literal in a value position.

fn from_bool(value: bool) -> Result<Self>

Create an instance from a bool literal in a value position.

impl ToTokens for DeriveInputShapeSet

fn to_tokens(&self, tokens: &mut TokenStream)

Write self to the given TokenStream.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self directly into a TokenStream object.
