Enum AttrPathspecError 

#[non_exhaustive]
pub enum AttrPathspecError {
    Empty,
    MultipleAttrClauses,
    InvalidName(String),
    DanglingEscape,
    UnsupportedEscape,
}

Why a :(attr:...) pathspec clause was rejected.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Empty

The clause names no attribute requirement (:(attr:)).

MultipleAttrClauses

More than one attr: clause appears in one pathspec.

InvalidName(String)

A requirement names an attribute that is not valid (-a=b, bad name, bad/name).

DanglingEscape

A \ escape ends the value or precedes whitespace.

UnsupportedEscape

A \ escape precedes something other than ,.
