Struct PAttrs 

pub struct PAttrs {
    pub doc: Vec<String>,
    pub facet: Vec<PFacetAttr>,
    pub repr: PRepr,
    pub rename_all: Option<RenameRule>,
    pub crate_path: Option<TokenStream>,
    pub errors: Vec<CompileError>,
    pub declared_traits: Option<DeclaredTraits>,
    pub auto_traits: bool,
}

Parsed attributes

Fields

doc: Vec<String>

An array of doc lines

facet: Vec<PFacetAttr>

Facet attributes specifically

repr: PRepr

Representation of the facet

rename_all: Option<RenameRule>

rename_all rule (if any)

crate_path: Option<TokenStream>

Custom crate path (if any), e.g., ::my_crate::facet

errors: Vec<CompileError>

Errors to be emitted as compile_error! during code generation

declared_traits: Option<DeclaredTraits>

Explicitly declared traits via #[facet(traits(...))] When present, we skip all impls! checks and only generate vtable entries for the declared traits.

auto_traits: bool

Whether #[facet(auto_traits)] is present When true, we use the old specialization-based detection. When false (and no declared_traits), we generate an empty vtable.

Implementations

impl PAttrs

pub fn parse(attrs: &[Attribute], display_name: &mut String) -> PAttrs

Parse attributes from a list of Attributes

pub fn has_builtin(&self, key: &str) -> bool

Check if a builtin attribute with the given key exists

pub fn is_repr_transparent(&self) -> bool

Check if #[repr(transparent)] is present

pub fn get_builtin_args(&self, key: &str) -> Option<String>

Get the args of a builtin attribute with the given key (if present)

pub fn facet_crate(&self) -> TokenStream

Get the facet crate path, defaulting to ::facet if not specified

pub fn has_any_namespaced(&self) -> bool

Check if any namespaced attribute exists (e.g., kdl::child, args::short)

When a namespaced attribute is present, rename on a container may be valid because it controls how the type appears in that specific context.

pub fn get_builtin_span(&self, key: &str) -> Option<Span>

Get the span of a builtin attribute with the given key (if present)

Trait Implementations

impl Clone for PAttrs

fn clone(&self) -> PAttrs

Returns a duplicate of the value.

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

Performs copy-assignment from source.
