§
bounds: Vec<GenericBound>
§
synthetic: bool
This is normally false
, which means that this generic parameter is
declared in the Rust source text.
If it is true
, this generic parameter has been introduced by the
compiler behind the scenes.
Example
Consider
ⓘ
pub fn f(_: impl Trait) {}
The compiler will transform this behind the scenes to
ⓘ
pub fn f<impl Trait: Trait>(_: impl Trait) {}
In this example, the generic parameter named impl Trait
(and which
is bound by Trait
) is synthetic, because it was not originally in
the Rust source text.

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.
