Trait Implementations

impl Clone for DocCfgHideShowValue

fn clone(&self) -> DocCfgHideShowValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DocCfgHideShowValue

impl Debug for DocCfgHideShowValue

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

Formats the value using the given formatter.

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

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

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

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

impl PartialEq for DocCfgHideShowValue

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PrintAttribute for DocCfgHideShowValue

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)

impl StableHash for DocCfgHideShowValue

fn stable_hash<__Hcx: StableHashCtxt>( &self, __hcx: &mut __Hcx, __hasher: &mut StableHasher, )
