Function trait_declaration 

pub fn trait_declaration(
    qualifiers: Vec<GeneratedToken>,
    name: GeneratedToken,
    parameters: Vec<Vec<GeneratedToken>>,
    supertraits: Vec<Vec<GeneratedToken>>,
    predicates: Vec<Vec<GeneratedToken>>,
    items: Vec<GeneratedToken>,
) -> Result<Vec<GeneratedToken>, Overflow>

One trait declaration with exact qualifiers, parameters, supertraits, predicates and associated items.

Qualifiers are emitted exactly before trait, so an unsafe trait remains explicit caller authority.

Errors

Returns Overflow where the associated-item body outgrows the declared generated-token magnitude.
