Struct FmtCtx

pub struct FmtCtx<'a> {
    pub translated: Option<&'a TranslatedCrate>,
    pub generics: BindingStack<Cow<'a, GenericParams>>,
    pub locals: Option<&'a Locals>,
    pub indent_level: usize,
}

Context for formatting.

Fields

translated: Option<&'a TranslatedCrate>

generics: BindingStack<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>

indent_level: usize

Implementations
