Trait Implementations

impl Clone for AlterTypeInstruction

fn clone(&self) -> AlterTypeInstruction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> CustomToTokens<'a> for AlterTypeInstruction

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

impl Debug for AlterTypeInstruction

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

Formats the value using the given formatter.

impl Display for AlterTypeInstruction

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

Formats the value using the given formatter.

impl FromStr for AlterTypeInstruction

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 AlterTypeInstruction

type Output = AlterTypeInstruction

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

impl PartialEq for AlterTypeInstruction

fn eq(&self, other: &AlterTypeInstruction) -> 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 AlterTypeInstruction

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.
