Covers the Attr struct (a key-value pair), the general-purpose Any constructor, and briefly introduces type-specific constructors like Bool, Duration, and Float64\. Explains that Any works for all types but type-specific constructors avoid runtime type assertions. 19 2. 2 [](https://daily.dev/posts/slog-groupattrs-cmhm9xwg4 "slog.GroupAttrs") Article Boldly Go · 8w slog.GroupAttrs Covers the difference between slog.Group and slog.GroupAttrs in Go's structured logging package, noting that GroupAttrs is more efficient but only accepts slog.Attr values with no mixed form. Provides a practical toAttrs helper function that replicates slog's internal logic for converting variadic any arguments (including both string key/value pairs and slog.Attr values) into a \[\]slog.Attr slice, useful when building custom slog wrapper utilities. 16 2 [See all Boldly Go archives](/sources/boldlygo/best-of) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@graph":[{"@type":"CollectionPage","@id":"https://daily.dev/sources/boldlygo/best-of/2026/07#page","url":"https://daily.dev/sources/boldlygo/best-of/2026/07","name":"Best Boldly Go Posts — July 2026","description":"The most upvoted Boldly Go posts from July 2026, curated by the daily.dev community.","isPartOf":{"@type":"WebSite","url":"https://daily.dev"}},{"@type":"ItemList","@id":"https://daily.dev/sources/boldlygo/best-of/2026/07#items","numberOfItems":2,"itemListElement":[{"@type":"ListItem","position":1,"url":"https://daily.dev/posts/the-attr-type-udhsolgm5","name":"The Attr type"},{"@type":"ListItem","position":2,"url":"https://daily.dev/posts/slog-groupattrs-cmhm9xwg4","name":"slog.GroupAttrs"}]},{"@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Sources","item":"https://daily.dev/sources"},{"@type":"ListItem","position":3,"name":"Boldly Go","item":"https://daily.dev/sources/boldlygo"},{"@type":"ListItem","position":4,"name":"Best of","item":"https://daily.dev/sources/boldlygo/best-of"},{"@type":"ListItem","position":5,"name":"July 2026"}]}]} ```
