Struct TextEdit 

pub struct TextEdit {
    pub span: Range<usize>,
    pub text: String,
}

Represents a text edit operation for incremental updates.

Text edits are used to apply changes to source text in an incremental manner, such as those received from LSP clients or other text editing operations. Each edit specifies a byte range to replace and the new text to insert in that range.

Examples

let edit = TextEdit {
    span: 4..9,           // Replace characters at positions 4-8
    text: "world".into(), // With the text "world"
};

Fields

span: Range<usize>

The byte range in the original text to be replaced (start..end)

text: String

The new text to insert in place of the specified range
