Trait Implementations

impl Clone for AlterTableInstruction

fn clone(&self) -> AlterTableInstruction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> CustomToTokens<'a> for AlterTableInstruction

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

impl Debug for AlterTableInstruction

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

Formats the value using the given formatter.

impl Display for AlterTableInstruction

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

impl FromStr for AlterTableInstruction

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self>

Parses a string s to return a value of this type.

impl Parse for AlterTableInstruction

type Output = AlterTableInstruction

fn parse(s: &mut StatementStream<'_>) -> Result<Self::Output>

impl PartialEq for AlterTableInstruction

fn eq(&self, other: &AlterTableInstruction) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ToTokens for AlterTableInstruction

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

where Self: Sized,

Convert self directly into a TokenStream object.
