Variants

Sensitive(KSensitive)

A sensitive attribute that specifies sensitivity information.

Invariants(InvariantInner)

An invariants attribute that specifies invariants for the type.

Opaque(KOpaque)

An opaque attribute that specifies opaque information.

DenyUnknownFields(KDenyUnknownFields)

A deny_unknown_fields attribute that specifies whether unknown fields are allowed.

DefaultEquals(DefaultEqualsInner)

A default attribute with an explicit value (#[facet(default = “myfunc”)])

Default(KDefault)

A default attribute with no explicit value (#[facet(default)])

Transparent(KTransparent)

A transparent attribute for containers

Other(Vec<TokenTree>)

Any other attribute represented as a sequence of token trees.

Trait Implementations

impl Debug for FacetInner

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

Formats the value using the given formatter.

impl Parser for FacetInner

fn parser(tokens: &mut TokenIter<'_>) -> Result<Self>

The actual parsing function that must be implemented. This mutates the tokens iterator directly. It should not be called from user code except for implementing parsers itself and then only when the rules below are followed.

impl ToTokens for FacetInner

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

Write &self to the given TokenStream.

fn to_token_iter( &self, ) -> ShadowCountedIter<'_, <TokenStream as IntoIterator>::IntoIter>

Convert &self into a TokenIter object.

fn into_token_iter<'a>( self, ) -> ShadowCountedIter<'a, <TokenStream as IntoIterator>::IntoIter>

where Self: Sized,

Convert self into a TokenIter object.

fn to_token_stream(&self) -> TokenStream

Convert &self into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self into a TokenStream object.

fn tokens_to_string(&self) -> String

Convert &self into a String object. This is mostly used in the test suite to compare the outputs. When the input is a &str then this parses it and returns a normalized String.
