Struct Context

Source
#[non_exhaustive]
pub struct Context<'ctx> { pub ident_generator: &'ctx mut dyn IdentGenerator, /* private fields */ }
Expand description

The context passed to each generation stage of Generatable types

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§ident_generator: &'ctx mut dyn IdentGenerator

The ident generator used to generate unique idents across all templates.
