Struct SyntaxNodeOrToken

A wrapper for either a syntax node (SyntaxNode) or a syntax token (SyntaxToken).

Implements

IEquatable<SyntaxNodeOrToken>

Namespace: Loretta.CodeAnalysis

Syntax

public readonly struct SyntaxNodeOrToken

Remarks

Note that we do not store the token directly, we just store enough information to reconstruct it. This allows us to reuse nodeOrToken as a token's parent.
