Trait MakeExt

Source
pub trait MakeExt<T>
where Self: MakeVisitor<T> + Sized + Sealed<MakeExtMarker<T>>,
{ // Provided methods fn debug_alt(self) -> Alt<Self> { ... } fn display_messages(self) -> Messages<Self> { ... } fn delimited<D>(self, delimiter: D) -> Delimited<D, Self> where D: AsRef<str> + Clone, Self::Visitor: VisitFmt { ... } }
Expand description

Extension trait providing MakeVisitor combinators.

Provided Methods§

Source

fn debug_alt(self) -> Alt<Self>

Wraps self so that any fmt::Debug fields are recorded using the alternate formatter ({:#?}).

Source

fn display_messages(self) -> Messages<Self>

Wraps self so that any string fields named “message” are recorded using fmt::Display.

Source

fn delimited<D>(self, delimiter: D) -> Delimited<D, Self>
where D: AsRef<str> + Clone, Self::Visitor: VisitFmt,

Wraps self so that when fields are formatted to a writer, they are separated by the provided delimiter.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors§
