Struct darling::util::Ignored
[−]
[src]
pub struct Ignored;
An efficient way of discarding data from an attribute.
All meta-items, fields, and variants will be successfully read into
the Ignored struct, with all properties discarded.
Trait Implementations
impl Debug for Ignored[src]
fn fmt(&self, __arg_0: &mut Formatter) -> Result<(), Error>[src]
Formats the value using the given formatter. Read more
impl Eq for Ignored[src]
impl FromVariant for Ignored[src]
fn from_variant(&Variant) -> Result<Ignored, Error>[src]
Create an instance from syn::Variant, or return an error.
impl Clone for Ignored[src]
fn clone(&self) -> Ignored[src]
Returns a copy of the value. Read more
fn clone_from(&mut self, source: &Self)1.0.0[src]
Performs copy-assignment from source. Read more
impl Copy for Ignored[src]
impl FromDeriveInput for Ignored[src]
fn from_derive_input(&DeriveInput) -> Result<Ignored, Error>[src]
Create an instance from syn::DeriveInput, or return an error.
impl Hash for Ignored[src]
fn hash<__H>(&self, __arg_0: &mut __H) where
__H: Hasher, [src]
__H: Hasher,
Feeds this value into the given [Hasher]. Read more
fn hash_slice<H>(data: &[Self], state: &mut H) where
H: Hasher, 1.3.0[src]
H: Hasher,
Feeds a slice of this type into the given [Hasher]. Read more
impl FromMetaItem for Ignored[src]
fn from_meta_item(&Meta) -> Result<Ignored, Error>[src]
Create an instance from a syn::Meta by dispatching to the format-appropriate trait function. This generally should not be overridden by implementers. Read more
fn from_nested_meta_item(&NestedMeta) -> Result<Ignored, Error>[src]
fn from_word() -> Result<Self, Error>[src]
Create an instance from the presence of the word in the attribute with no additional options specified. Read more
fn from_list(items: &[NestedMeta]) -> Result<Self, Error>[src]
Create an instance from a list of nested meta items.
fn from_value(value: &Lit) -> Result<Self, Error>[src]
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. Read more
fn from_char(value: char) -> Result<Self, Error>[src]
Create an instance from a char literal in a value position.
fn from_string(value: &str) -> Result<Self, Error>[src]
Create an instance from a string literal in a value position.
fn from_bool(value: bool) -> Result<Self, Error>[src]
Create an instance from a bool literal in a value position.
impl PartialEq<Ignored> for Ignored[src]
fn eq(&self, __arg_0: &Ignored) -> bool[src]
This method tests for self and other values to be equal, and is used by ==. Read more
fn ne(&self, other: &Rhs) -> bool1.0.0[src]
This method tests for !=.
