Soenneker.Extensions.Spans.Chars

Allocation-free helpers for clearing character buffers and writing pre-sized long values.

Installation

dotnet add package Soenneker.Extensions.Spans.Chars

Clear sensitive characters

using Soenneker.Extensions.Spans.Chars;

Span<char> password = stackalloc char[64];
// Fill and use password...
password.SecureZero();

SecureZero() clears the bytes backing the entire span through CryptographicOperations.ZeroMemory, so the write cannot be optimized away. It mutates only the supplied span; copies of the secret remain the caller's responsibility.

Write an integer into a prepared buffer

using Soenneker.Extensions.Spans.Chars;

const long value = -12345;
Span<char> buffer = stackalloc char[6];

buffer.WriteInt64(value, digits: 6);
string text = new(buffer); // "-12345"

WriteInt64() and WritePositiveInt64() are low-level formatting helpers for code that already knows the exact output length. They avoid allocations, but intentionally do not calculate or validate digits.

WriteInt64() accepts the full long range. digits includes the minus sign.
WritePositiveInt64() requires a non-negative value. digits is the number of decimal digits.
The destination must contain at least digits characters.
An incorrect digit count can leave characters unwritten or cause indexing to fail. Use long.TryFormat() when the output length is not already known.
