Enum ParamKind 

pub enum ParamKind {
    Inline(InlineOptions),
    Import(ImportRoot),
    Format(Format),
    Source(FieldRef),
    Transparent(Transparent),
    From,
}

The kind of meta-parameter.

Variants

Inline(InlineOptions)

The inline behavior of the error type.

Import(ImportRoot)

The import root of the error type.

Format(Format)

The format string of the error type.

Source(FieldRef)

The source-forwarding behavior of the error type.

Transparent(Transparent)

A transparent error type.

This is useful for new-type wrappers that are transparent over some other type.

From

The from forwarding behavior of the error type.

This is useful for new-type wrappers that are completely opaque to the error type.

Trait Implementations

impl Clone for ParamKind

fn clone(&self) -> ParamKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParamKind

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

Formats the value using the given formatter.

impl Hash for ParamKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ParamKind

fn eq(&self, other: &ParamKind) -> 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.
