2025-09-10internal/runtime/maps: remove redundant package docsxieyuschen
This CL removes redundant package docs comments under different files as all of them will be shown in pkgsite. As of now, package docs 'Package maps implements Go's builtin map type' appears 3 times in pkgsite.

2025-07-30all: remove redundant Swiss prefixesMichael Pratt
Now that there is only one map implementation we can simplify names. For #54766.

Use the new SwissTable-based map in internal/runtime/maps as the basis for the runtime map when GOEXPERIMENT=swissmap. Integration is complete enough to pass all.bash. Notable missing features: * Race integration / concurrent write detection * Stack-allocated maps * Specialized "fast" map variants * Indirect key / elem For #54766.

2024-10-08internal/runtime/maps: initial swiss table map implementationMichael Pratt
Add a new package that will contain a new "Swiss Table" (https://abseil.io/about/design/swisstables) map implementation, which is intended to eventually replace the existing runtime map implementation. This implementation is based on the fabulous github.com/cockroachdb/swiss package contributed by Peter Mattis. This CL adds an hash map implementation. It supports all the core operations, but does not have incremental growth. For #54766.
