Fields and properties (4)

public int Start
Zero-based character offset of the first character.
public int Length
Number of characters covered.
public int End
One past the last character. Exclusive, so an empty span has End == Start.
public bool IsEmpty
Whether the span covers no characters.

public TextSpan(int Start, int Length)
An immutable half-open interval [Start, End) into source text, measured in characters. The primary currency for spans and diagnostics.
public static bool operator <(TextSpan left, TextSpan right)
Orders by Start, then by Length.
public static bool operator <=(TextSpan left, TextSpan right)
public static bool operator >(TextSpan left, TextSpan right)
public static bool operator >=(TextSpan left, TextSpan right)
public bool Contains(int position)
Whether falls inside the span. End is excluded.
public bool Contains(TextSpan span)
Whether lies entirely within this one.
public bool OverlapsWith(TextSpan other)
Whether the two spans share at least one character. Touching spans do not overlap.
public static TextSpan FromBounds(int start, int end)
Builds a span from inclusive to exclusive .
public int CompareTo(TextSpan other)
Orders by Start, breaking ties with Length.
public override string ToString()
Renders as [start..end), matching the half-open convention.
