Trait Implementations

impl Clone for ColumnDefault

fn clone(&self) -> ColumnDefault

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> CustomToTokens<'a> for ColumnDefault

fn to_tokens(&'a self, tokens: &mut TokenStream)

impl Debug for ColumnDefault

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ColumnDefault

fn fmt(&self, f: &mut Formatter<'_>) -> Result

fn to_tokens(&self, tokens: &mut TokenStream)

Write self to the given TokenStream.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStream
