The particular reason for a ParseError

Variants

UnknownLicense

The specified license short-identifier was not found the SPDX list

UnknownException

The specified exception short-identifier was not found the SPDX list

InvalidCharacters

The characters are not valid in an SDPX license expression

UnclosedParens

An opening parens was unmatched with a closing parens

UnopenedParens

A closing parens was unmatched with an opening parens

Empty

The expression does not contain any valid terms

Unexpected(&'static [&'static str])

Found an unexpected term, which wasn’t one of the expected terms that is listed

SeparatedPlus

A + was found after whitespace, which is not allowed by the SPDX spec

UnknownTerm

When lexing, a term was found that was

1. Not a license short-id
2. Not an exception short-id
3. Not a document/license ref
4. Not an AND, OR, or WITH

GnuNoPlus

GNU suffix licenses don’t allow + because they already have the -or-later suffix to denote that

Trait Implementations

impl Debug for Reason

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

Formats the value using the given formatter.

impl Display for Reason

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

Formats the value using the given formatter.

impl PartialEq for Reason

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