Code for resolving name grid lines and areas

Structs

AreaLines 🔒

The one-indexed positions of the first line that starts and the first line that ends a named grid area in each axis, i.e. the first line named <area-name>-start/<area-name>-end (explicitly or by grid-template-areas). A value of 0 means that there is no such line.

GridLineNames

The names of each explicit grid line in a single axis, stored in CSR (compressed sparse row) format: a single flat Vec of names plus a Vec of offsets into it (one more offset than there are lines). The names of line i (0-indexed) are names[offsets[i]..offsets[i + 1]].

GridLineNamesIter

Iterator over the per-line name groups of a GridLineNames. Yields one &[S] per grid line (which is empty for unnamed lines)

NamedLineResolver 🔒

Resolver that takes grid lines names and area names as input and can then be used to resolve line names of grid placement properties into line numbers.

NamedLineResolverAxis 🔒

Resolver for named placements in one grid axis

StrHasher 🔒

Wrap an AsRef<str> type with a type which implements Hash by first deferring to the underlying &str’s implementation of Hash.

Functions

oz_line 🔒

The named line maps store lines as 1-based “CSS Grid Line” numbers (which are always within the explicit grid). Convert one to OriginZero coordinates.

split_area_edge_name 🔒

Split a line name of the form <area-name>-start or <area-name>-end into the area name and the edge

upsert_line_name_map 🔒

Utility function to create or update an entry in a line name map

Type Aliases

GridAreasMap 🔒

Map from the name of a grid area to the lines of its edges.

LinePositions 🔒

The one-indexed line positions of a single grid line name. Inline capacity of 4 keeps the type the same size as Vec<u32> (24 bytes) while avoiding a heap allocation for names mapping to at most 4 lines (the common case)

NamedGridLinesMap 🔒

Map from a grid line name to its one-indexed line positions
