Struct DeclaredTraits 

pub struct DeclaredTraits {

    pub display: bool,
    pub debug: bool,
    pub clone: bool,
    pub copy: bool,
    pub partial_eq: bool,
    pub eq: bool,
    pub partial_ord: bool,
    pub ord: bool,
    pub hash: bool,
    pub default: bool,
    pub send: bool,
    pub sync: bool,
    pub unpin: bool,
}

Tracks which traits are explicitly declared via #[facet(traits(...))].

When this is present, we skip all impls! checks and only generate vtable entries for the declared traits.

Fields

display: bool

Display trait declared

debug: bool

Debug trait declared

clone: bool

Clone trait declared

copy: bool

Copy trait declared (marker)

partial_eq: bool

PartialEq trait declared

eq: bool

Eq trait declared (marker)

partial_ord: bool

PartialOrd trait declared

ord: bool

Ord trait declared

hash: bool

Hash trait declared

default: bool

Default trait declared

send: bool

Send trait declared (marker)

sync: bool

Sync trait declared (marker)

unpin: bool

Unpin trait declared (marker)

Implementations

impl DeclaredTraits

pub fn has_any(&self) -> bool

Returns true if any trait is declared

pub fn parse_from_tokens( tokens: &TokenStream, errors: &mut Vec<CompileError>, ) -> DeclaredTraits

Parse traits from a token stream like Debug, PartialEq, Clone, Send

Trait Implementations

impl Clone for DeclaredTraits

fn clone(&self) -> DeclaredTraits

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for DeclaredTraits

fn default() -> DeclaredTraits

Returns the “default value” for a type.
