The specific kind of error underlying an Error.

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.

Message(String)

A custom error message from Serde

Io(String)

An I/O error, carrying the underlying error’s message

Eof

Unexpected end of input

Syntax

Syntax error in the input

ExpectedBoolean

Expected a boolean value

ExpectedInteger

Expected an integer value

ExpectedFloat

Expected a float value

ExpectedString

Expected a string value

ExpectedArray

Expected an array

ExpectedArrayComma

Expected a comma in an array

ExpectedArrayEnd

Expected end of array

ExpectedArraySemicolon

Expected a semicolon after array

ExpectedList

Expected a list

ExpectedListComma

Expected a comma in a list

ExpectedListEnd

Expected end of list

ExpectedGroup

Expected a group (struct)

ExpectedEquals

Expected an equals sign or colon

ExpectedSemicolon

Expected a semicolon

ExpectedCommaOrSemicolon

Expected a comma or semicolon

ExpectedGroupEnd

Expected end of group

ExpectedIdentifier

Expected an identifier

TrailingCharacters

Trailing characters after parsing

HeterogeneousArray

Heterogeneous arrays are not supported

InvalidEscape

Invalid escape sequence

InvalidNumber

Invalid number format

KeyMustBeAString

Maps with non-string keys are not supported

UnitNotSupported

Unit type not supported at top level

TypeNotSupported(String)

Type not supported

IntegerOutOfRange

Integer value does not fit in the target type

FloatOutOfRange

Float value does not fit in the target type

NonFiniteFloat

Non-finite floats (inf, NaN) cannot be represented in libconfig

InvalidSettingName(String)

Setting name does not match [A-Za-z*][-A-Za-z0-9_*]*

InvalidPath(String)

Path passed to lookup/set/remove is malformed

PathTraversal(String)

A path traversal step failed (wrong container type or missing index)

ArrayElementNotScalar

Arrays may only contain scalar values

TopLevelBraces

Braces around the top level of a configuration are not allowed (grammar: a configuration is a setting list; braces delimit nested groups only)

UnterminatedComment

A /* block comment was never closed with */ (section 2.10 defines block comments as delimited pairs)

Include(String)

Error processing an @include directive
