STextRange

A range in a text document/string expressed as (zero-based) begin and end row/column.

API > API/Runtime > API/Runtime/uLangCore

A range in a text document/string expressed as (zero-based) begin and end row/column. A range is comparable to a selection in an editor. Therefore the end position is exclusive. Columns are byte offsets into the UTF-8 encoded line.

To specify a range that contains a line including the line ending character(s), use an end position denoting the start of the next line (or) same row and the column just past the last character on the row.

Often used with CUTF8StringView and SIdxRange. CUTF8StringView should do the converting to and from SIdxRange and STextRange.

Similar to a LSP Range - https://microsoft.github.io/language-server-protocol/specifications/specification-3-14/#range Also similar to UE `FIntRect_
