Expand description
Equivalent to syn::Fields
, but replaces the AST element with a generic.

pub fn empty_from(vd: &Fields) -> Self
sourcepub fn split(self) -> (Style, Vec<T>)
pub fn split(self) -> (Style, Vec<T>)
Splits the Fields
into its style and fields for further processing.
Returns an empty Vec
for Unit
data.
sourcepub fn is_newtype(&self) -> bool
pub fn is_newtype(&self) -> bool
Returns true if this variant’s data makes it a newtype.

pub fn is_struct(&self) -> bool
pub fn as_ref(&self) -> Fields<&T>
pub fn map<F, U>(self, map: F) -> Fields<U>where F: FnMut(T) -> U,
