This is an example of documentation generated by ZigDoc, an alternative to Zig's built-in Auto Doc feature. See also examples in other modes/formats. The project being documented here (as the example) is the Zig standard library. Public Function

peekSentinel

Public Function
std.Io.Reader.peekSentinel
pub fn peekSentinel(r: *Reader, comptime sentinel: u8) DelimiterError![:sentinel]u8

Returns a slice of the next bytes of buffered data from the stream until sentinel is found, without advancing the seek position.

Returned slice has a sentinel; end of stream does not count as a delimiter.

Invalidates previously returned values from peek.

Errors

ReadFailed

See the Reader implementation for detailed diagnostics.

EndOfStream

For "inclusive" functions, stream ended before the delimiter was found. For "exclusive" functions, stream ended and there are no more bytes to return.

StreamTooLong

The delimiter was not found within a number of bytes matching the capacity of the Reader.
