Function bufPrint [src]

Print a Formatter string into buf. Actually just a thin wrapper around format and fixedBufferStream. Returns a slice of the bytes printed to.

Prototype

pub fn bufPrint(buf: []u8, comptime fmt: []const u8, args: anytype) BufPrintError![]u8

Parameters

buf: []u8fmt: []const u8

Possible Errors

NoSpaceLeft

As much as possible was written to the buffer, but it was too small to fit all the printed bytes.

Source

  pub fn bufPrint(buf: []u8, comptime fmt: []const u8, args: anytype) BufPrintError![]u8 {
    var fbs = std.io.fixedBufferStream(buf);
    format(fbs.writer().any(), fmt, args) catch |err| switch (err) {
        error.NoSpaceLeft => return error.NoSpaceLeft,
        else => unreachable,
    };
    return fbs.getWritten();
}
