Types

type Diagnostic 

type Diagnostic struct {
	Range    Range    `json:"range"`
	Severity Severity `json:"severity,omitempty"`
	Code     any      `json:"code,omitempty"`
	Source   string   `json:"source,omitempty"`
	Message  string   `json:"message"`
}

func DiagnosticsFromProtocol 

func DiagnosticsFromProtocol(values []lsp.Diagnostic) []Diagnostic

type Position 

type Position struct {
	Line      int `json:"line"`
	Character int `json:"character"`
}

type Range 

type Range struct {
	Start Position `json:"start"`
	End   Position `json:"end"`
}

type SemanticToken 

type SemanticToken struct {
	Line      int      `json:"line"`
	Character int      `json:"character"`
	Length    int      `json:"length"`
	Type      string   `json:"type"`
	Modifiers []string `json:"modifiers,omitempty"`
}

SemanticToken is the expanded editor representation shared by the LSP and Tree-sitter providers. The LSP client itself keeps the protocol's raw, delta-encoded SemanticTokens value.

type Service 

type Service struct {
	// contains filtered or unexported fields
}

Service owns the code-intelligence backends for one workspace. It is the only layer that chooses between language-server and structural results.
