Struct FmtCtx

source
pub struct FmtCtx<'a> {
    pub translated: Option<&'a TranslatedCrate>,
    pub generics: VecDeque<Cow<'a, GenericParams>>,
    pub locals: Option<&'a Locals>,
}
Expand description

For formatting.

Note that we use the ULLBC definitions, even when formatting LLBC definitions. It doesn’t really matter, as all we use is the name of the definitions.

Remark: we take shared borrows to the top-level declarations, but clone the generics, because we may dive into different contexts and may need to update those. We can think of a smarter way of doing this, but for now it is simple and efficient enough.

Fields§

§translated: Option<&'a TranslatedCrate>§generics: VecDeque<Cow<'a, GenericParams>>

Generics form a stack, where each binder introduces a new level. For DeBruijn indices to work, we keep the innermost parameters at the start of the vector.

§locals: Option<&'a Locals>
