Cast is a Go library that provides easy and safe conversion (casting) between different types in Go programs. Especially when dealing with interface{} or dynamic/reflect-heavy code, it becomes cumbersome to assert types or convert values reliably; cast addresses that by offering a suite of functions to convert from any input to the target type with predictable behaviour. Rather than relying purely on raw type assertions, it offers ToInt, ToString, ToBool, ToTime, etc., and their...

...Benchmarks also show similar performance gains compared to pure for loops. In the future, 5 to 10 helpers will overlap with those coming into the Go standard library (under package names slices and maps). I feel this library is legitimate and offers many more valuable abstractions.

This package is a high-performance, in-memory B-tree for Go that implements an ordered set/map with efficient insert, delete, and range iteration. It’s parameterized by tree degree so callers can tune cache behavior and memory overhead for their workload. Instead of relying on Go’s built-in maps—which are hash-based and unordered—btree preserves sorted order and provides rich traversal APIs like ascending, descending, and range scans. The implementation favors minimal allocations and locality, making it attractive for indexing, query engines, and caches that need predictable iteration costs. A simple Item interface with a Less method defines ordering, keeping the API small and flexible for custom types. ...

This repository holds the Uber Go Style Guide, which documents patterns and conventions used in Go code at Uber. Styles are the conventions that govern our code. The term style is a bit of a misnomer, since these conventions cover far more than just source file formatting—gofmt handles that for us. The goal of this guide is to manage this complexity by describing in detail the Dos and Don'ts of writing Go code at Uber. These rules exist to keep the code base manageable while still allowing...

...This structure allows students to quickly jump to specific topics in the video without scrubbing blindly through the timeline. The syllabus goes from environment setup and basic syntax to types and variables, constants and operators, control statements, arrays, slices, maps, functions, structs, methods, interfaces, reflection, and concurrency, before finishing with a “projects and pitfalls” session.

Package envconfig implements decoding of environment variables based on a user-defined specification. Typical use is using environment variables for configuration settings. Envconfig supports the use of struct tags to specify alternate, default, and required environment variables. Envconfig won't process a field with the "ignored" tag set to "true", even if a corresponding environment variable is set. Any field whose type (or pointer-to-type) implements envconfig.Decoder can control its own...
