pub struct Label<FileId> {
    pub style: LabelStyle,
    pub file_id: FileId,
    pub range: Range<usize>,
    pub message: String,
}
Expand description

A label describing an underlined region of code associated with a diagnostic.

Fields§

§style: LabelStyle

The style of the label.

§file_id: FileId

The file that we are labelling.

§range: Range<usize>

The range in bytes we are going to include in the final snippet.

§message: String

An optional message to provide some additional information for the underlined code. These should not include line breaks.
