InvariantViolationException (fantomas)

InvariantViolationException Type

Namespace: Fantomas.Core
Assembly: Fantomas.Core.dll
Base Type: FormatException
All Interfaces: ISerializable

Raised when Fantomas reaches a state that its own model says is impossible, for example a chain whose parts do not fit the shape the transformer guarantees. Unlike the other exceptions here, this never indicates a problem with the code being formatted: it is a bug in Fantomas, or a change in how the F# parser groups expressions. Failing loudly is deliberate — the alternative is silently dropping parts of the source.

Constructors

Constructor	Description
`InvariantViolationException(msg, range)` Full Usage: `InvariantViolationException(msg, range)` Parameters: msg : `string` range : `range` Returns: `InvariantViolationException`	msg : `string` range : `range` Returns: `InvariantViolationException`
`InvariantViolationException(msg, range, syntaxNode)` Full Usage: `InvariantViolationException(msg, range, syntaxNode)` Parameters: msg : `string` range : `range` syntaxNode : `string` Returns: `InvariantViolationException`	msg : `string` range : `range` syntaxNode : `string` Returns: `InvariantViolationException`

Instance members

Instance member	Description
`this.Invariant` Full Usage: `this.Invariant` Returns: `string`	The invariant that was violated, on one line, without the location or the "please report" suffix. A caller that positions the violation against the source itself reports this and draws the rest from `Range`. Returns: `string`
`this.Range` Full Usage: `this.Range` Returns: `range`	The source range of the construct that triggered the violation. Returns: `range`
`this.SyntaxNode` Full Usage: `this.SyntaxNode` Returns: `string`	The syntax tree node that triggered the violation, dumped in full, or an empty string when there is none to show. This is what a maintainer triaging the issue needs and what whoever filed it does not, so it is kept off the message and reported at detailed verbosity. Returns: `string`
