Struct cglue_gen::trait_groups::TraitGroup

pub struct TraitGroup { /* fields omitted */ }

Describes parse trait group, allows to generate code for it.

Implementations

impl TraitGroup

pub fn optional_group_ident<'a>(
    name: &Ident,
    postfix: &str,
    traits: impl Iterator<Item = &'a TraitInfo>
) -> Ident

Identifier for optional group struct.

Arguments

• name - base name of the trait group.
• postfix - postfix to add after the naem, and before With.
• traits - traits that are to be implemented.

pub fn optional_func_name<'a>(
    prefix: &str,
    lc_names: impl Iterator<Item = &'a TraitInfo>
) -> Ident

Get the name of the function for trait conversion.

Arguments

• prefix - function name prefix.
• lc_names - lowercase identifiers of the traits the function implements.

pub fn enable_opt_vtbls<'a>(
    iter: impl Iterator<Item = &'a TraitInfo>
) -> TokenStream

Generate function calls that enable individual functional vtables.

Arguments

• iter - iterator of optional traits to enable

pub fn create_group(&self) -> TokenStream

Generate full code for the trait group.

This trait group will have all variants generated for converting, building, and converting it.

pub fn vtbl_where_bounds<'a>(
    iter: impl Iterator<Item = &'a TraitInfo>,
    container_ident: TokenStream,
    this_ident: TokenStream,
    ctx_ident: TokenStream,
    ctx_opaque_ident: TokenStream
) -> TokenStream

Bind Default to mandatory vtables.
