Trait Implementations

impl Clone for EntEdgeDeletionPolicy

fn clone(&self) -> EntEdgeDeletionPolicy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EntEdgeDeletionPolicy

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

Formats the value using the given formatter.

impl Default for EntEdgeDeletionPolicy

fn default() -> Self

Returns the “default value” for a type.

impl FromMeta for EntEdgeDeletionPolicy

fn from_list(__outer: &[NestedMeta]) -> Result<Self>

Create an instance from a list of nested meta items.

fn from_string(lit: &str) -> Result<Self>

Create an instance from a string literal in a value position.

pub fn from_nested_meta(item: &NestedMeta) -> Result<Self, Error>

pub fn from_meta(item: &Meta) -> Result<Self, Error>

Create an instance from a syn::Meta by dispatching to the format-appropriate trait function. This generally should not be overridden by implementers.

pub fn from_word() -> Result<Self, Error>

Create an instance from the presence of the word in the attribute with no additional options specified.

pub fn from_value(value: &Lit) -> Result<Self, Error>

Create an instance from a literal value of either foo = "bar" or foo("bar"). This dispatches to the appropriate method based on the type of literal encountered, and generally should not be overridden by implementers.

pub fn from_char(value: char) -> Result<Self, Error>

Create an instance from a char literal in a value position.

pub fn from_bool(value: bool) -> Result<Self, Error>

Create an instance from a bool literal in a value position.
