switch

An example of catch |err| switch(err).

Frustration

Searching for a type, this type depends on a sub-type, which depends on the OS, which ultimately... cannot be documented automatically.

Example:

std.fs.File.Mode => const Mode: "mode_t" = os.mode_t;
os.mode_t => const mode_t: "mode_t" = system.mode_t;

anytype

// create a server path for the UNIX socket based on the service name
pub fn server_path(self: *Self, service_name: []const u8, writer: anytype) !void {
    try writer.print("{s}/{s}", .{ self.rundir, service_name });
}

From var buffer: [1000]u8 = undefined; var fbs = std.io.fixedBufferStream(&buffer); var writer = fbs.writer(); try ctx.server_path("simple-context-test", writer); var path = fbs.getWritten(); To var buffer: [1000]u8 = undefined; var path = try std.fmt.bufPrint(&buffer, "{s}/{s}", .{ ctx.rundir, "simple-context-test" });

Errors

Double returning type => no need for specific return structures.

Timer

const Timer = std.time.Timer;
var timer = try Timer.start();
var duration = timer.read() / 1000000; // ns -> ms

var value = db.get(key) orelse return error.notHere;

There is still room for improvement.

When the result actually is a single value (anonymous hash). src/switch.zig:125:37: error: binary operator | has whitespace on one side, but not the other. self.db.fetchSwapRemove(fd) |k,v|{
