[−]
[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 Copy for Ignored[src]
impl Hash for Ignored[src]
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.
