label_type

Definition

Diagnostic label identifying a region of source text.

A label highlights a specific character range within a source line and may carry an explanatory message. Labels are used to produce compiler-style diagnostics similar to those of rustc or clang.

Labels may be primary or secondary:

• Primary labels identify the principal cause of the diagnostic.
• Secondary labels provide additional context.

Primary labels determine the source location shown in the diagnostic header and are rendered using '^' markers.

Secondary labels are rendered using '-' markers and provide supplementary context.

Note

Character positions are 1-based. The highlighted range spans:

first <= position < finish

where finish is exclusive.

Examples

type(string) :: s
s = 'foo'
