ErrorType<'T, 'State> (XParsec) | XParsec

ErrorType<'T, 'State> Type

Namespace: XParsec
Assembly: XParsec.dll
Base Type: obj
All Interfaces: IEquatable<ErrorType<'T, 'State>> , IStructuralEquatable

Describes why a parser failed. The default formatParseError renders these in a tree, but consumers are free to pattern-match and emit their own format.

Union cases

Union case	Description
`Empty` Full Usage: `Empty`	Unspecified failure — analogous to FParsec's "empty error message list". Produced by `pzero`. Aggregating combinators filter `Empty` children before constructing nested errors, and the default formatter renders nothing.
`EndOfInput` Full Usage: `EndOfInput`	The parser hit end-of-input but expected more.
`Expected 'T` Full Usage: `Expected 'T` Parameters: Item : `'T`	A specific item was expected at this position. Item : `'T`
`ExpectedOneOf 'T seq` Full Usage: `ExpectedOneOf 'T seq` Parameters: Item : `'T seq`	One of several alternative items was expected. Item : `'T seq`
`ExpectedSeq 'T seq` Full Usage: `ExpectedSeq 'T seq` Parameters: Item : `'T seq`	A specific sequence of items was expected. Item : `'T seq`
`ExpectedSeqOneOf 'T seq seq` Full Usage: `ExpectedSeqOneOf 'T seq seq` Parameters: Item : `'T seq seq`	One of several alternative sequences was expected. Item : `'T seq seq`
`Message string` Full Usage: `Message string` Parameters: Item : `string`	A free-form parser-supplied message. Item : `string`
`Nested(parent, children)` Full Usage: `Nested(parent, children)` Parameters: parent : `ErrorType<'T, 'State>` children : `ParseError<'T, 'State> list`	A `parent` error caused by the listed `children` (typical for combinators like `<\|>`, `choice`, and the `*Till` family that aggregate sub-errors). parent : `ErrorType<'T, 'State>` children : `ParseError<'T, 'State> list`
`Unexpected 'T` Full Usage: `Unexpected 'T` Parameters: Item : `'T`	An item was encountered that should not have been. Item : `'T`
`UnexpectedSeq 'T seq` Full Usage: `UnexpectedSeq 'T seq` Parameters: Item : `'T seq`	A sequence of items was encountered that should not have been. Item : `'T seq`
