Trait Implementations

impl Clone for DeprecatedFunction

fn clone(&self) -> DeprecatedFunction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeprecatedFunction

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

Formats the value using the given formatter.

impl Display for DeprecatedFunction

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

Formats the value using the given formatter.

impl<'_derivative_strum> From<&'_derivative_strum DeprecatedFunction> for &'static str

fn from(x: &'_derivative_strum DeprecatedFunction) -> &'static str

Converts to this type from the input type.

impl From<&DeprecatedFunction> for Rc<dyn FunctionDefinition>

fn from(value: &DeprecatedFunction) -> Self

将已废弃函数枚举转换为函数定义

为每个已废弃函数创建相应的函数定义，保持向后兼容性

impl From<DeprecatedFunction> for &'static str

fn from(x: DeprecatedFunction) -> &'static str

Converts to this type from the input type.

impl FromStr for DeprecatedFunction

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<DeprecatedFunction, <Self as FromStr>::Err>

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

impl Hash for DeprecatedFunction

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IntoEnumIterator for DeprecatedFunction

type Iterator = DeprecatedFunctionIter

fn iter() -> DeprecatedFunctionIter

impl PartialEq for DeprecatedFunction

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

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

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 TryFrom<&str> for DeprecatedFunction

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from( s: &str, ) -> Result<DeprecatedFunction, <Self as TryFrom<&str>>::Error>

Performs the conversion.

impl Copy for DeprecatedFunction

impl Eq for DeprecatedFunction

impl IsEnabled for DeprecatedFunction

impl StructuralPartialEq for DeprecatedFunction
