Trait Implementations

impl Clone for DEMethod

fn clone(&self) -> DEMethod

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DEMethod

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

Formats the value using the given formatter.

impl Default for DEMethod

fn default() -> DEMethod

Returns the “default value” for a type.

impl Display for DEMethod

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

Formats the value using the given formatter.

impl From<DEMethod> for Field

fn from(method: DEMethod) -> Self

Converts to this type from the input type.

impl FromStr for DEMethod

type Err = Error

The associated error which can be returned from parsing.

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

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

impl PartialEq for DEMethod

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl TryFrom<Field> for DEMethod

type Error = Box<dyn Error>

The type returned in the event of a conversion error.

fn try_from(field: Field) -> Result<Self>

Performs the conversion.

impl Copy for DEMethod

impl Eq for DEMethod

impl StructuralPartialEq for DEMethod
