Extension for syn::Meta

Required methods

`fn is_path(&self) -> bool`

Returns true if self matches syn::Meta::Path

`fn is_list(&self) -> bool`

Returns true if self matches syn::Meta::List

`fn is_name_value(&self) -> bool`

Returns true if self matches syn::Meta::NameValue

`fn promote_to_list(&mut self, paren: Paren) -> Result<&mut MetaList>`

Promotes to empty syn::Meta::List with given paren if syn::Meta::Path

A syn::Meta::Path value can be regarded as an empty syn::Meta::List. promote means converting syn::Meta::Path to an actual empty syn::Meta::List.

`fn list(&self) -> Result<&MetaList>`

Returns syn::MetaList of syn::Meta::List; Otherwise Err

`fn list_mut(&mut self) -> Result<&mut MetaList>`

Returns syn::MetaList of syn::Meta::List; Otherwise Err

`fn name_value(&self) -> Result<&MetaNameValue>`

Returns syn::MetaNameValue of syn::Meta::NameValue; Otherwise Err

`fn name_value_mut(&mut self) -> Result<&mut MetaNameValue>`

Returns syn::MetaNameValue of syn::Meta::NameValue; Otherwise Err
