Struct SyntheticAttrState

Source

pub(crate) struct SyntheticAttrState {
    cfg_trace: ThinVec<(CfgEntry, Span)>,
    cfg_attr_trace: bool,
}

Expand description

This struct contains the state necessary to convert synthetic attributes to hir attributes The only conversion that really happens here is that multiple synthetic 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 SyntheticAttr::CfgTrace attributes.

§cfg_attr_trace: bool

Attribute state for SyntheticAttr::CfgAttrTrace attributes. The arguments of these attributes is no longer relevant for any later passes, only their presence. So we discard the arguments here.
