impl Param[src]

pub fn to_self(&self) -> Option<ExplicitSelf>[src]

Attempts to cast parameter to ExplicitSelf.

pub fn is_self(&self) -> bool[src]

Returns true if parameter is self.

pub fn from_self(
    attrs: AttrVec,
    eself: ExplicitSelf,
    eself_ident: Ident
) -> Param

Builds a Param object from ExplicitSelf.
