Variants

GenericParam

Fields

generic_param: Symbol

span: Span

SelfUpper

This

{This} or {TraitName}

Trait

The sugared form of the trait

ItemContext

what we’re in, like a function, method, closure etc.

AsIs(Symbol)

What the user typed, if it doesn’t match anything we can use.

Trait Implementations

impl Clone for FormatArg

fn clone(&self) -> FormatArg

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FormatArg

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

Formats the value using the given formatter.

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

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

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

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

impl<__CTX> HashStable<__CTX> for FormatArg

where __CTX: HashStableContext,

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

impl PrintAttribute for FormatArg

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.
