EarlyParsedState

Struct EarlyParsedState 

Source
pub(crate) struct EarlyParsedState {
    cfg_trace: ThinVec<(CfgEntry, Span)>,
    cfg_attr_trace: bool,
}
Expand description

This struct contains the state necessary to convert early parsed attributes to hir attributes The only conversion that really happens here is that multiple early parsed attributes are merged into a single hir attribute, representing their combined state. FIXME: We should make this a nice and extendable system if this is going to be used more often

Fields§

§cfg_trace: ThinVec<(CfgEntry, Span)>

Attribute state for #[cfg] trace attributes

§cfg_attr_trace: bool

Attribute state for #[cfg_attr] trace attributes The arguments of these attributes is no longer relevant for any later passes, only their presence. So we discard the arguments here.
