taffy = { version = "0.9.2", default-features = false, features = ["block_layout", "flexbox", "grid", "calc", "content_size", "detailed_layout_info", "strict_provenance", "taffy_tree", "serde", "std", "alloc", "debug", "profile", "document-features"] }

default = block_layout, calc, content_size, detailed_layout_info, flexbox, grid, std, taffy_tree

These default features are set whenever taffy is added without default-features = false somewhere in the dependency tree.

block_layout default

calc default

Enables calc() values for all layout algorithms

content_size default

Causes all algorithms to compute and output a content size for each node

Affects layout::LayoutOutput.content_size, layout::Layout.content_size…

detailed_layout_info default
