Struct NameValue 

pub struct NameValue {
    pub name: Name,
    pub value: FilterFormatString,
}

A MetaNameValueStr in an on-filter.

For example, #[rustc_on_unimplemented(on(name = "value", message = "hello"))].

Fields

name: Name

value: FilterFormatString

Something like "&str" or "alloc::string::String", in which case it just contains a single string piece. But if it is something like "&[{A}]" then it must be formatted later.

Implementations

impl NameValue

pub fn visit_params(&self, span: Span, visit: &mut impl FnMut(Symbol, Span))

Trait Implementations

impl Clone for NameValue

fn clone(&self) -> NameValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NameValue

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

Formats the value using the given formatter.

impl<__D: SpanDecoder> Decodable<__D> for NameValue

fn decode(__decoder: &mut __D) -> Self

impl<__E: SpanEncoder> Encodable<__E> for NameValue

fn encode(&self, __encoder: &mut __E)

impl<__CTX> HashStable<__CTX> for NameValue

where __CTX: HashStableContext,

fn hash_stable(&self, __hcx: &mut __CTX, __hasher: &mut StableHasher)

impl PrintAttribute for NameValue

fn should_render(&self) -> bool

Whether or not this will render as something meaningful, or if it’s skipped (which will force the containing struct to also skip printing a comma and the field name).

fn print_attribute(&self, __p: &mut Printer)

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
